Abstract

A system and method for force-starting a voltage and current controlled element is disclosed. In a simplified embodiment, a power source is coupled to the controlled element via a start-up circuit. The start-up circuit supplies a current, or voltage, to the controlled element, responsive to the voltage or current level at a specified node being below a threshold level. Preferably, two diode-connected devices may be utilized, thereby providing current forcing capability when the voltage level at the specified node is below a threshold voltage level, as specified by the diode-connected devices.
