As to the generalized auxiliary converters, it is difficult to achieve their lightweight design due to their properties of large capacity and volume. To address this issues, an improved auxiliary converter is proposed in this paper, which has the following advantages: 1) The proposed topology directly takes power from the DC high-voltage bus and effectively reduces the conversion order of the entire converter. 2) The charger adopts bidirectional isolated DC-DC converter to realize bidirectional energy transmission, which can overcome the disadvantage that the traditional structure cannot maintain the power supply of the AC bus when the pantograph loses power. In addition, for the DC-DC converter and inverter in this structure, the corresponding mathematical models are established and the related control strategies are applied to ensure the whole system normal operation and finally verified by simulation and experimental results.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116397342","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}

Accordingly, a considerable number of flexible power point tracking (FPPT) algorithms are introduced in the literature. The aim of such algorithms is to regulate the PV power to a specific value rather than continuously track the maximum power point. This power reference value is calculated based on the operation condition and grid requirements. This paper provides a short description of several available FPPT algorithms in the literature, and studies various features of each algorithm. The dynamic performance of the investigated algorithms is compared using experimental tests on a scaled-down prototype. The comparison reveals that the FPPT algorithms with direct calculation of the voltage reference, which corresponds to the required power reference, provide better performance in all aspects.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123031478","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 proposed ionizer mainly consists of a resonant circuit and a magnetizing inductance control circuit to feature advantage of simple structure. For the proposed multi-function, the resonant circuit generates a high voltage AC sine wave having peak value 4 kV and the sine wave is inputted to a voltage multiplier to generate the other selectable AC 4 kV square wave. The magnetizing inductance control circuit introduces a magnetizing current into a designed winding of transformer to vary the magnetizing force and permeability of transformer and to tune the magnetizing inductance for the resonant frequency adjustment, so and the frequency of sine wave or square wave. The magnetizing inductance control circuit also feedbacks the high voltage square wave to monitor whether the positive high voltage equals the negative high voltage to implement the ionization balance performance.

However, if the balance of the primary side current is not maintained, the magnetizing inductance of the transformer is saturated and can be damaged. Therefore, it is crucial to balance the primary side current through the peak current mode control. During the peak current control mode, subharmonic oscillation occurs when the duty is 0.5 or more. Therefore, it is suppressed by slope compensation. The slope depends on the output voltage. Because it is difficult to change the slope in real time depending on the output voltage, the maximum slope value is selected to suppress the subharmonic oscillation for all values of duty ratio. Nevertheless, when the maximum slope value is used, the response speed is delayed because of overcompensation. To solve these problems, hybrid current mode control that combines both peak and valley current mode control has been proposed. This study proposes a hybrid current mode control method for PSFB converters, while considering the magnetizing current and ineffective duty. When this method is used, subharmonic oscillation does not occur for all duty ratio values and input/output voltage fluctuations.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128671280","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 main drawback of IPT is not only eddy-current losses generated by magnetic fields in the foreign object located in the air-gap but also the pad size and total cost considerations. This paper implements a four-plate compact capacitive coupler for suficient air-gap distance CPT as proposed by other scientific paper. The four-plate arrangement is also designed by referring to the previous research which results in a good coupling capacitance. The LCL compensation is utilized to resonate with the four plates coupler. The resonant network equation is proposed in previous research by employing the superposition theorem to analyze the two AC sources in the coupler separately. Whereas, this paper proposes the resonant analysis by implementing wye-delta and delta-wye transform in the equivalent impedance network. Hence, that approach could bring a contribution by generating a gain curve for further study. The circuit model is simulated in PSIM software to verify the gain curve and specific resonant parameter. The ANSYS Maxwell software is employed to simulate the coupler design. Finally, a 260-W prototype of the CPT system with a 60-mm air-gap distance is constructed and experimentally tested to validate the gain curve and mathematical analysis for the equivalent impedance network, as the main focus of this research.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129801863","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 requirement of high step-up gain of voltage compromises the efficiency of this converter due to the increased conduction loss in the low voltage side of the transformer. This paper presents a GaN-based isolated dc-dc converter that achieves both high step-up voltage gain and high efficiency with minimal component count. The converter utilizes a half-bridge series-resonant circuit, with duty-ratio controlled pulse width modulation. A new equivalent circuit of the primary side network of the converter is proposed that determines the optimum values of magnetizing inductance and deadtime for minimizing circulating current without affecting the soft-switching of the switches. The design is verified with a 240W laboratory prototype.
