Abstract

A solenoid driver operable to drive a solenoid actuating a high-voltage power switch is disclosed. The solenoid driver includes a first group of semiconductor switches including a first semiconductor switch and a second semiconductor switch in series. This group is connected to a high-voltage supply line by a diode. The solenoid driver further includes a second group of semiconductor switches including a third semiconductor switch and a fourth semiconductor switch in series. This group is connected to the high-voltage supply line by a second diode. The solenoid driver further includes a common connection between the first group of semiconductor switches and the second group of semiconductor switches. A solenoid coil of the solenoid is connected between the first group of semiconductor switches and the second group of semiconductor switches at a junction between the first and second semiconductor switches and a junction between the third and fourth semiconductor switches.
