Abstract
According to one aspect, a starter-generator control unit may include a comparator, a pulse width modulation (PWM) duty cycle generator, a randomizer, and a sequencer. The comparator may receive a current reading from a current sensor and a target current from a target current lookup table and generate an output comparator signal indicative of an increase or a decrease in a current value of a pulse width modulation (PWM) duty cycle. The PWM duty cycle generator may receive the signal from the comparator and generate an output PWM signal. The randomizer may generate a randomly time-varying update signal. The PWM duty cycle generator may receive the randomly time-varying update signal which may control a cycle time associated with the PWM duty cycle generator. The sequencer may receive the output PWM signal and generate a gate control signal for controlling an inverter based on the output PWM signal.
