Abstract :
PDM-dual control adapted to a set rectifier - parallel resonant inverter makes it possible to implement an AC/AC converter with good performances (cost, size, efficiency and power-factor). The main disadvantage of this AC/AC converter is a bad distribution of the current in semiconductor switches. To solve this problem, we propose a more suitable form of this control: linear PDM-dual control. It is based on a linear modulation of the PDM duty cycle. A theoretical analysis is achieved and results are validated by simulation.
