Abstract:
Dead time compensated complementary pulse width modulation (PWM) signals are derived from a PWM generator by first applying time period compensation to the PWM generator signal based upon the direction of current flow in an inductive load being controlled by the PWM generator. Dead time is then applied to the compensated PWM generator signal for producing complementary dead time compensated PWM signals for controlling power switching circuits driving the inductive load.
