“…It runs in a stand-alone configuration and can provide its outputs also in formats compatible with commercial programs such as MATLAB. SapWinPE validity is demonstrated by the examples shown in the paper and by its successful application to power converter fault diagnosis and resonant converter design [47][48][49][50][51].…”

The problem of Pulse Width Modulated (PWM) DC-DC converter simulation is faced in this paper. It is shown how the analysis of this kind of circuits, nonlinear and switching for their nature, can be easily and quickly executed by using symbolic analysis techniques. The paper also presents the program SapWinPE, which performs an automatic symbolic analysis of the considered circuit, and its outputs are in MATLAB compatible format. SapWinpPE features make it more attractive than general-purpose software tools for both academy and industry circuit designers. Other characteristics and potentialities, shown through application examples in the paper, can be advantageously exploited by all the circuit designers and CAD professionals, also at the research and educational level in the academic field.

“…Since the input impedance of the proposed resonant circuit is controlled at the inductive load, Q 1~Q8 can be turned on under zero voltage switching. The power loss analysis of the resonant converter or inverters has been discussed in [17,18] for fixed switching frequency. However, the switching frequency of the resonant converter is variable.…”

A new resonant converter is presented to have the advantages of soft switching operation on power devices, without reverse recovery current loss on power diodes and wide input voltage range operation. Resonant converter with frequency modulation is adopted in the proposed circuit to accomplish the low switching loss on power switches and possible zero current switching operation on fast recovery diodes. To improve the problem of limit voltage range operation in the conventional resonant converter, a new parallel-series structure resonant converter is studied to achieve wide input voltage operation capability, such as from Vin,min to 4Vin,min. A 1.8 kW laboratory circuit is implemented, and the measured results are provided to confirm the theoretical analysis and circuit performance.

“…Researchers have provided accurate time domain analysis waveforms and a parameter design approach for the half-bridge Class DE [42,43]. On this basis, the steady-state time-domain analysis of the full-bridge Class DE was proposed [44]. However, few people have investigated the application of Class DE inverters in wireless power transfer, although some researchers have described the use of half-bridge Class DE inverters in WPT systems at low power, which enables low-power and high-efficiency power transfer at fixed loads [45].…”

In high-frequency wireless power transfer (WPT) applications, Class D, E, and F inverters are most widely used. Class DE inverters combine the respective advantages of Class D and Class E inverters. However, the Class DE inverter is sensitive to changes in impedance, which can easily lead to the loss of soft switching characteristics, thereby reducing efficiency. In this paper, an impedance-matching compensation design method is proposed to expand the high-efficiency region of the Class DE inverter by matching impedance and parameters. The effect of the method on the zero-voltage switching (ZVS) characteristic of Class DE inverters is analyzed in detail. The proposed WPT system maintains a constant voltage and zero phase angle by employing PS/PS compensation topology. Theoretical analysis shows that the impedance can be compressed for the design of resonant network impedance, and the method can expand the high-efficiency region with a reasonable choice of parameters to match the phase. Finally, a 500 kHz, 1 kW WPT prototype was constructed with a coupling factor of 0.25–0.4 and a load range of 30–80 Ω. The inverter’s efficiency exceeds 95%, with optimal efficiency reaching 97.3%. The system efficiency is greater than 87%.
