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 ...

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

Losses in soft-switched and hard-switched voltage inverters
2003 IEEE International Symposium on Industrial Electronics ( Cat. No.03TH8692), 2004This paper introduces an adequate loss model, based on the experimental results, which can be used to estimate the losses in hard-switched and soft-switched inverters. As an example and considering the use of IGBTs, it compares the losses produced by hard-switched, auxiliary resonant commutated pole (ARCP) and quasi-square-wave (QSW) inverters for ...
