In the majority of commercial products, a fixed-frequency current mode control (CMC) technique is used. This requires an over-compensated ramp for current-loop stability, which would tend to degrade the phase margin using a type-II compensator. Constant off-time (COFT) CMC may not require any ramp compensation and can achieve superior performance. However, suitable design methods are not readily available to identify performance limits using fixed-frequency and COFT CMC architectures. This paper presents the small-signal design and performance limitations of a type-II controller in CMC architectures. Thereafter, a trajectory-based design approach is developed to identify critical performance limits using a resettable PI controller, which can achieve near time-optimal performance with and without a peak current limit. Start-up performance is shown to be further improved by using a low voltage LED string, however, at the cost of an increasing pin count. Finally, a method is identified to achieve smooth controller transitions in a peak current-based constant on/off-time multi-mode controller. Experimental results of a few commercial LED drivers with their performance limits are presented, and for the same specs, the performance improvement using the proposed design framework is demonstrated using simulation results.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115406092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the reliable operation of power converters depends on satisfactory performance of all critical components at cryogenic temperature. While most of the critical components have been studied at cryogenic temperatures, some electronic components necessary for electrical isolation in signal circuits of a medium voltage power converter are yet to be evaluated extensively. This work studies the cryogenic performance of isolated auxiliary power supplies (APS), digital isolators, fiber optics, and isolation amplifiers to identify the well-performing candidates and to investigate the possible reason of failures at cryogenic temperatures. It is observed that some isolated APS with high isolation voltage and isolation amplifiers can work satisfactorily at cryogenic temperatures. The digital isolators are found to be more suitable for cryogenic operation than fiber optic links, even though the latter has better noise immunity.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115705349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the fast switching speed and surge impedance mismatch between cables and motors, this overvoltage can be two times or even higher than the DC-bus voltage of the inverter, resulting in motor insulation degradation or irreversible breakdown. The most common solution to mitigate such overvoltage is to install a dv/dt or a sinewave filter at the output of the drive, which decreases the efficiency and power density of the system. Among different stator coils, the first one (close to the drive side) is the most susceptible to insulation breakdown since it experiences higher overvoltage than the others due to the nonlinear distribution of the reflected surge voltages. In this paper, an innovative high-efficiency ultracompact mitigation solution is introduced, which is a tiny auxiliary circuit embedded inside the motor stator (or at the motor terminal box), specifically across the first few coils of each phase (i.e., smart coils). The proposed smart coil circuit effectively mitigates the surge overvoltage, which can be scalable to any type of motor-drive systems, regardless of cable length and semiconductor rise time. The proposed solution can dramatically improve the reliability, efficiency, and power density of motor-drive systems.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123156908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the reciprocating movement of the pistons, sensors cannot be connected to the cars electrical system by wires and thus are usually powered by batteries. Changing those batteries is a time consuming process since large parts of the engine needs to be taken apart to get to the pistons. This is the reason why we present a system that uses a piezoelectric nano generator (PENG) based on flexible PVDF to convert a small amount of the mechanical energy of the pistons to electrical energy. A power management system (PMS) including a maximum power point (MPP) circuit maximizes the power output of the harvester and supplies a regulated dc voltage to the sensor. The MPP circuit used in this design has a very few components, thus keeping its own power consumption low. It requires a minimum input voltage of 3V and a minimum power of 1.4µW during operation. During startup, a power of 4µW is required for a short time until the input capacitor of thre PMS is charged to 1.8V. Measurements show an increase of up to 44% of harvested power while also allowing higher output voltages compared to the same power management system without an MPP circuit. A prototype to emulate the movement of the pistons was built and tested with the PENG and PMS. At 600rpm, data transmission is possible every 90 seconds with 3.5µW harvested power.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115831405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To combat this challenge, electrifying the aircraft is a promising solution. Howbeit, the idea of aircraft electrification is introducing various dc power distribution architectures, increasing the complexity of aircraft electric power systems (EPS). The aircraft EPS is of low voltage and makes the system handle huge currents. Alongside this, the next-generation aircraft power system demands faster and more reliable protection. Solid-state circuit breakers (SSCBs) offer fast fault interruption capability and make the protection system compact. This article proposes a modified Q-Z-source (MQZSCB) dc circuit breaker (DCCB) topology that employs a thyristor as the main fault-interrupting device and uses a coupled inductor for its commutation during faults. Also, it employs fewer components, thereby reducing the weight/volume of the system, which benefits the design aspects of the aircraft. The proposed topology can interrupt the fault approximately within $400mu {mathrm{s}}$. Moreover, this topology is advantageous to the existing QZSCB by mitigating the issues of negative current flow through the load, especially during reclosing, and unwanted power flow to the load during the QZSCB commissioning. The proposed solution also enables reduced current stress on the thyristor during reclosing. A prototype rated at 270V/10A has been developed to address the issues and validate the performance of the proposed MQZSCB.","PeriodicalId":151216,"journal":{"name":"2023 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127190706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
