1. A method for gating a power supply, comprising:
- capacitively coupling a gating command terminal to an on/off switch;
providing a positive voltage source and a negative voltage source at the on/off switch;
providing a gating command signal at the gating command terminal, the gating command signal operable to activate the on/off switch;
generating an off signal at an output terminal of the on/off switch in response to an off state of the on/off switch being activated, a pulse width of the off signal being less than a pulse width of the gating command signal; and
generating an on signal at the output terminal of the on/off switch in response to an on state of the on/off switch being activated, a pulse width of the on signal being less than the pulse width of the gating command signal.

Abstract
The present invention comprises a method for gating a power supply. A gating command terminal is capacitively coupled to an on/off switch. A gating command signal is provided at the gating command terminal. The gating command signal is operable to activate the on/off switch. An off signal is generated at an output terminal of the on/off switch in response to an off state of the on/off switch being activated. An on signal is generated at the output terminal in response to an on state of the on/off switch being activated.
