摘要: This paper explores predictive digital current programmed control for valley, peak or average current. The laws are derived the three basic converters: buck, boost, and buck-boost. It is found that each variable of interest (valley, current) there a choice appropriate pulse-width modulation method to achieve without oscillation problems. proposed techniques can be used in range power conversion applications, including rectifiers with factor correction (PFC). Very low distortion meeting strict avionics requirements (400-800 Hz line frequency) experimentally demonstrated on digitally controlled boost PFC employing control.
