Abstract:
An energy delivery circuit, comprising:a first input terminal adapted to be connected to a first power supply; a second input terminal adapted to be connected to a second power supply; a first output terminal; a second output terminal; a first power-supply-coupling switch coupled between the first input terminal and the first output terminal, wherein the first power-supply-coupling switch is adapted to latch conduction between a voltage from the first power supply to the first output terminal in only a single quadrant of a current versus voltage graph; a second power-supply-coupling switch coupled between the first input terminal and the second output terminal, wherein the second power-supply-coupling switch is adapted to latch conduction between a voltage from the first power supply to the second output terminal in only a single quadrant of a current versus voltage graph; a first trigger switch coupled to the first power-supply-coupling switch to couple the high voltage from the first power supply to the first output terminal; and a second trigger switch coupled to the second power-supply-coupling switch to couple the high voltage from the first power supply to the second output terminal.
