A predictive current control for three-phase PWM rectifiers is proposed to simplify the design of the current loop with less memory and interrupt resource occupation in a digital signal processor. Together with the decomposition-matrix method, the total algorithm can be completed with only one timer and its underflow interrupt subroutine. The predictive current controller helps to design the voltage...
Numerical simulation methodology based on high frequency mathematical model of high power factor PWM rectifier is proposed in this paper. And input to output transform function is deduced. With the help of input to output transform function, the design method of voltage regulator has been presented. The simulation for three-phase PWM rectifier is implemented with Runge-Kutta, thus comprehensive simulation...

Inner current loop modeling of a resonant DC link inverter, soft switching combination inverter, which works in current controlled three state discrete pulse modulation mode, is proposed. The modeling method is valid for double loop feedback controlled inverters which works in other modulation mode. Equivalent analytic model is established and used for voltage regulator design. Example are given in...
