Abstract
An active clamp, three-phase, six-switch power factor correction rectifier with a one-cycle controller is proposed, which can effectively suppress the reverse recovery of the reverse parallel diode of the bridge arm switch and reduce the reverse recovery loss. The main switches and auxiliary switch are both zero-voltage switches. It works in a fixed switching frequency and low power stress during the switching period. The specific working process and control circuit are analyzed in detail, and the model simulation is carried out. The experimental platform of a 2.5 KW prototype, with a complete test and verification of the soft switch technology proposed in this paper, was set up in the laboratory.
Highlights
The early three-phase power factor correction (PFC) (PFC) rectifier is derived from the single-phasePFC rectifier system and/or passive three-phase diode rectifier [1,2]
A bridgeless, four-switch, three-phase rectifier is proposed in reference [5], and it can operate with any pulse width modulation (PWM)
Lin C.W proposed a soft-switching assist circuit for a three-phase six-switch rectifier was used to achieve zero voltage switching (ZVS) in the main switches and zero current switching (ZCS) in the auxiliary switch, and consists of an auxiliary switch, a resonant inductor, a transformer, three barrier diodes, and a clamp RDC circuit [11]. Another soft switching circuit is proposed by Nagai, S that has only two active power semiconductor devices, which consists of one auxiliary resonant commutated pole link (ARCPL) circuit and one ARDCL circuit
