... 1F- vdc Vienna topology (M =1 ), the most popular PWM boost-type PFC concept with three voltage levels. By adding auxiliary Filter/ PWM PWM Transformer/ active power device(s) to 1F-Vienna circuit and through proper Rectifier Inverter Grid modulation strategies, the ripple frequency present in the input (a) ...
