Claim Text:
1. A solid state relay circuit comprising: a control circuit that receives a master control signal and generates first and second control signals; a fast turn-on circuit that receives the first and second control signals in an isolated manner, that operates in an enabled state when the first and second control signals have first values, and that switches to a disabled state when the first and second control signals have second values; a fast turn-off circuit that receives the first and second control signals in an isolated manner, that operates in a disabled state when the first and second control signals have the first values, and that switches to an enabled state when the first and second control signals have the second values; a power switching circuit that enables a source power to be supplied to a load when the fast turn-on circuit is in the enabled state and the fast turn-off circuit is in the disabled state, and disables the source power from being supplied to the load when the fast turn-on circuit is in the disabled state and the fast turn-off circuit is in the enabled state; and a power supply circuit that provides isolated power to the fast turn-on circuit and the fast turn-off circuit and that drives the power switching circuit when the fast turn-on circuit is in the enabled state and the fast turn-off circuit is in the disabled state, the isolated power being disabled from driving the power switching circuit when the fast turn-on circuit is in the disabled state and the fast turn-off circuit is in the enabled state, the power supply circuit comprising:
