The input inductors are operated in continuous conduction mode (CCM) while the EDR stage inductors are operated in discontinuous conduction mode (DCM) to attain the benefits of both CCM and DCM operation. The low input current ripple due to interleaving and low voltage stress of the EDR stage switches are retained. With the proposed hybrid mode of operation, the inductance value of EDR stage inductor reduces significantly. A further reduction in switch voltage is achieved during turn-on transition in the proposed operation, leading to significant reduction in turn-on switching losses. This enables converter operation at higher switching frequency, thus, reducing the size of EDR inductors by 45% in this case. The proposed concept is verified experimentally by a 2-phase Q-EDR hardware prototype operating at 30 V-40 V to 400 V output, easily achieving a gain above 12 at duty close to 0.54. The converter is able to achieve a peak efficiency of 95.5% at 300 W, 135 kHz switching frequency with all silicon switches.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115323554","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}

While conventional modulation techniques, including Space Vector Modulation (SVM), can be readily adapted to these new topologies, the very fast dynamic underlying the resonant transitions and resonance sequence enabled by the resonant tank(s) require additional attention. This paper proposes two simple, reliable and ultra-fast sensing circuits together with robust control mechanisms to ensure proper timing and control of the resonant tank(s). With this new approach, device stress is mitigated even under larger converter transients or fault conditions, and the soft-switching operation is guaranteed, including in applications with wide variations of source and load voltages (e.g., motor drives) or for multi-port converters interfacing multiple sources and loads operating at different voltages and frequencies.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121261350","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}

This parameter can have significant interactions with the power input stages of equipment or appliances, such as the performance of EMI filters and the sensitivity of protection devices. These effects can vary widely by location and construction of industrial, commercial, and residential power systems and in some cases exhibit high variation within a single location. Unfortunately, line impedance has been historically difficult to measure and characterize as it is distributed along the length of each feed from the source. This paper describes an innovative technique to determine line impedance by loading the system to generate a large impulse current which produces a significant voltage sag without the need for intricate switching logic and circuitry. This method will be validated empirically on a 120V residential electrical system and compared to LTspice simulation results to confirm accuracy.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123459292","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}

The converter can be used as variable and highly efficient DC power supply of GaN solid state power amplifiers (SSPA) in E-band as opposed to the conventional low dropout regulators, improving the overall SSPA power efficiency. The converter (0.036 in3) achieves an overall efficiency of above 80 % over nearly the whole output voltage range and a peak efficiency of $> 91%$, depending on the gate resistor, at a power density of above 300 W/in3. The achieved voltage peak amplitude varies from below 20 mV to above 200 mV, again strongly depending on the value of the gate resistor. The AC voltage ripple is below 2 mV for all converter designs, making it suitable for low-noise supply of the power amplifiers drain terminals and to replace the conventional inefficient low-dropout voltage regulators. A comprehensive analysis of the tradeoff between switching speed, efficiency and high-/low frequency voltage noise is carried out to highlight the potential of GaN based low-noise DC/DC supplies. Finally, measurements are performed with different DC supplies (LDO, switch-mode power supply unit, and the GaN DC/DC converter from this work) with an E-band transmission chain to demonstrate the usability of this approach. It can be seen that the GaN DC/DC converter supplies the SSPA with no difference to the state-of-the-art solutions and does not cause any oscillations/instabilities, but can increase the efficiency of the power amplifier by 40 %.","PeriodicalId":127006,"journal":{"name":"2022 IEEE Applied Power Electronics Conference and Exposition (APEC)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129515483","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}
