Analysis and improvement on input characteristics of VIENNA converter with inductive filter and one-cycle-control method

Input characteristics of L-filtered pulse-width-modulation (PWM) converter with one-cycle-control (OCC) method was analyzed, and the contradiction between decreasing phase displacement angle and decreasing input current ripple was revealed when the maximum switching frequency was limited to ensure h...

Description
Summary:Input characteristics of L-filtered pulse-width-modulation (PWM) converter with one-cycle-control (OCC) method was analyzed, and the contradiction between decreasing phase displacement angle and decreasing input current ripple was revealed when the maximum switching frequency was limited to ensure high system efficiency. Given this, LCL-filtering scheme was introduced and used on OCC PWM converter, and the inductor current sampling scheme was proposed combined with frequency domain analysis of the system. Finally, experimental results were given to prove validity of the provided filtering scheme and the current sampling strategy.
