The brushless direct current motor (BLDCM) has high torque, compact size, and high efficiency. Therefore, BLDCM is widely used in computers, household and industrial products, and automobiles. It is usually driven by a hard-switching pulse width modulation (PWM) inverter, which has low switching frequency, high switching loss, high electro-magnetic interference (EMI) and acoustic noise, etc. To solve the drawbacks of ...

This paper first presents a hybrid-switching step-down dc-dc converter, and then, by introducing transformer isolation, a novel hybrid-switching phase- shift full-bridge dc-dc converter is derived for electric vehicle battery chargers. The proposed converter provides wide zero-voltage-switching range in the leading-leg switches, achieves zero-current-switching for lagging-leg switches, and uses a hybrid-switching method to avoid freewheeling circulating losses in the primary side. ...

This paper presents a comparative study between an improved full-bridge (FB) zero-voltage and zero-current switching (ZVZCS) phase-shifted pulsewidth modulation (PS-PWM) DC-DC converter and an improved three-level (TL) ZVZCS PS- PWM DC-DC converter. Both converters operate at fixed frequency and achieve zero-voltage-switching on the leading leg of FB or outer switches of TL, and also achieve zero-current-switching on lagging leg of ...

A zero-voltage switching-zero-current switching interleaved boost converter is proposed in this paper. An active circuit branch in parallel with the main switches is added and it is composed of an auxiliary switch and a snubber capacitor. By using this interleaved converter topology, zero current turn-on and zero voltage turn-off of the main switches can be achieved and the reverse-recovery loss ...

A new soft-switched, current-driven full-bridge converter is presented. The structure utilizes a simple snubber formed by two unidirectional switches and a capacitor to realize soft-switching operation over a wide line and load range. All primary-side switches are operated with zero-current switching (ZCS) and the snubber switches are operated with zero-voltage switching. The energy used for soft-switching is self-adaptable. For a ...
