Abstract :
The application of pulse density modulation (PDM) control to a rectifier-series resonant inverter set makes it possible to implement an AC/AC converter with good performances (size and efficiency). However its power factor decreases when the load power varies. We propose a dual-PDM control strategy adapted to a rectifier - parallel resonant inverter set. This converter is obtained by application of the rules of the duality to a series-resonant-inverter. The main interests of this converter are a self power factor correction and a step-up load power. Dual-PDM control law is defined and converter modeling is carried out. Results are validated by simulation.
