A Single-Stage Soft-Switching AC/DC Converter without Soft-Switching Auxiliary Circuit
2019 IEEE International Conference on Industrial Technology (ICIT), 2019This paper proposed a single-stage soft-switching AC/DC converter without soft-switching auxiliary circuit. The proposed AC/DC converter only uses two main active switches to execute the input power factor correction and regulate the output dc voltage magnitude.

Research on Switching Power Supply Based on Soft Switching Technology
2020Aiming at the problem that it is difficult to realize zero voltage and zero current switching (ZVZCS) in the current switching power supply, the resonance energy of the lagging arm is insufficient. In this paper, with TMS320F2812 as the control core, the DC/DC part of the switching power supply is designed by using the PWM phase shift control full ...

Analysis of soft synchronous commutations in switching converters
2000 IEEE International Symposium on Circuits and Systems (ISCAS), 2000In this paper a new method for the analysis of soft synchronous commutations in switching converters is presented. The method is based on the application of the compensation principle, and allows one to perform jointly the analysis of both hard and soft synchronous commutations.

The soft-switching buck inverter, which is mainly applied to solve the contradictions between the switching frequency and the shoot-through problem along with the dead-time effect, is proposed in this paper. A detailed analysis of the relationship between the range of the duty ratio to realize soft-switching as well as the additional voltage stress and

Switch-mode power converters are used in a wide variety of applications. In most applications, it is desirable to design high-frequency switching power converters to increase their power density. However, the switching losses are increased by increasing the frequency. Moreover, large dv/dt and di/dt produce electromagnetic interference. To minimize the
