Abstract :
FPGA technologies realize very fast digital calculation capability with 1MHz order data sampling feedback in power electronics field. A new approach of precise digital control method of 1MHz variable multi sampling deadbeat control combined with multi-rate control method using FPGA based hardware controller using ultra high speed Rocket I/O network for feedback signals is proposed. Applying three kinds of discrete time model, PWM pulse width is recalculating every 1μ second while the carrier interval based on multi-rate deadbeat control. A good transient response and robustness can be realized. Through simulations and experiments, verification is carried out.
