ACTUATOR DRIVER CIRCUIT

摘要

A circuit for driving an actuator including a closing coil and an opening coil, the circuit including a first electrical switch, a second electrical switch, a third electrical switch, a first diode, a second diode, a third diode, and a capacitor electrically connected to a second terminal of the third electrical switch. The circuit is structured such that controlling the state of the first, second, and third transistors causes current flowing through the circuit to flow through one of the closing coil and the opening coil and to not flow through the other of the closing coil and the opening coil.
