Abstract
A solenoid drive circuit includes a power source, a first solenoid control circuit connected to the power source, the first solenoid control circuit including a first solenoid coil and a first solenoid control switch that controls a flow current through the first solenoid coil and a first regenerative drive circuit connected to the first solenoid control circuit and that includes a first regenerative capacitor. The first regenerative drive circuit can include a first diode bridge formed of four diodes (D1, D2, D3 and D4) and that has a positive input, a negative input, a positive output and a negative output, wherein the first regenerative capacitor is connected between the positive and negative inputs.
