Abstract
In one embodiment, a system for reducing component noise in a motor in a automobile includes a first gate driver and a second gate driver, a high side FET; a low side FET; a charge pump circuit; a high frequency reduction component; and a timing signal source. The timing source signal interconnected to the charge pump, the first gate driver, and the second gate driver, the first gate driver interconnected with the charge pump, the first gate driver interconnected with the high side FET, the high side FET and the low side FET interconnected with the high frequency reduction component, the timing signal source providing timing signals to the signals to the first gate driver, the second gate driver, and the charge pump circuit such that the PWM slope is dull enough to prevent RE EMC, wherein the timing signal source provides three timing signals.
