Abstract :
The parallel resonant link high frequency converter is advantageous to realize a light weight and low EMI system. This paper presents a novel transient analysis method based on probability switching function, which is suited for PDM (pulse density modulation) controlled resonant link type converters. By using the proposed method, a high frequency parallel resonant link can be equivalently considered as a DC link capacitor, which makes it easier to analyze macroscopic transient response and/or design of the closed-loop control system. To confirm the validity of the proposed modeling method, closed-loop control of the link voltage has been done both in simulation and experiment
