Dual channel power switching: testing different PWM configurations

Switching power between battery and dump load is an important functionality of a charge controller. Switching fast by means of PWM allows for efficient battery charging: the battery (bank) is charged with an appropriate algorithm (bulk, absorption, float, pulse) while unnecessary energy is diverted to a dump load. Since relays are not well-suited for fast PWM switching, […]
