ABSTRACT:
This invention relates to a drive circuit coupled to electrical devices, which may be semiconductors, connected in parallel in a circuit network. The electrical devices have distinct total on-time periods when they are simultaneously energized. The circuit network has a source of power coupled through the parallel connected devices to a load. The drive circuit includes a signal source coupled respectively through a time adjustable circuit to a first electrical device and to a second electrical device. The time adjustable circuit is adjusted such that the total on-time of the first electrical device matches the total on-time of the second electrical device to thereby ensure equal power at all times through the electrical devices to the load. The invention allows a number of parallel devices to act as a single switch.
