For higher power application, the six-switch three-phase boost rectifier is a preferred topology. Compared with three-phase three-wire boost rectifier, the three-phase four-wire input rectifier is more usually used in uninterrupted power supply (UPS) systems to prevent the load neutral from floating. In this paper, the four-wire input boost PFC rectifier is modeled and analyzed; the origin of the...
PWM plus phase-shift (PPS) control technique is a technique combining PWM control technique and phase-shift control technique. PPS control bidirectional DC-DC converters have two regulating parameters, that is duty cycle D and phase-shift angles Phi. The paper proposed a new technique based on state-space averaging technique for modeling PWM plus phase-shift (PPS) controlled active clamping boost...
In three-phase PFC converter, there exist severe switch antiparallel diode reverse recovery problems. The effective measures of compound active-clamping and minimal voltage active-clamping techniques in single phase PFC are extended to three-phase PFC. A family of active-clamping ZVS soft switching PFC converter is derived. They can effectively suppress the diode reverse recovery and realize ZVS for...
PWM is introduced to phase-shift bidirectional dc-dc converters, which can reduce current stresses, conduction loss and switching loss of semiconductors and can expand ZVS range. A technique to synthesize PWM plus phase-shift bidirectional dc-dc converter topologies is presented. Theoretical analysis, simulation and experimental results of one particular converter taken as an example, are provided...
