Abstract
The invention provides an apparatus for shunting leakage current of a solid state switching device (SSSD) (). The apparatus selectively provides a shunt pathway to divert current away from the output load based on the switching state of the SSSD. The apparatus may include a shunt impedance component () connected to the SSSD, and a switching element () for selectively connecting the other end of the shunt impedance component to ground based on the switching state of the SSSD. Accordingly, when the SSSD is turned off, the switching element is switched to a state that connects the shunt impedance component to ground, thereby shunting leakage current.
