ACTUATOR DRIVER CIRCUIT
First Claim
1. A circuit for driving an actuator including a closing coil having a first end and a second end and an opening coil having a first end and a second end, the circuit comprising:
- a first electrical switch having a first terminal electrically connected to the second end of the closing coil;
a second electrical switch having a first terminal electrically connected to the second end opening cold;
a third electrical switch having a first terminal electrically connected to the first ends of the closing and opening coils;
a first diode having an anode electrically connected to the second end of the closing coil;
a second diode having an anode electrically connected to the second end of the opening coil;
a third diode electrically connected to the first ends of the closing and opening coils; and
a capacitor electrically connected to a second terminal of the third electrical switch,wherein the circuit is structured such that controlling the state of the first, second, and third electrical switches 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.

Abstract
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.
