ABSTRACT:
An AC power line current regeneration method and circuitry energizes an AC power line from a DC power source through pulse width modulated switch means. The method and circuitry involves sampling the required peak line regeneration current value from a previous PWM cycle, I(peak last), sampling line regeneration current value at turn-on of the switch means, I(turn-on), and calculating the required peak line regeneration current value for the present PWM cycle, I(peak present), from both I(peak last) and I(turn-on).
