回路。In a switching element overvoltage prevention circuit provided at both ends of a switching element, a series-connected reverse current prevention diode and an overvoltage absorbing capacitor are provided at both ends of the switching element. A Zener diode and a resistor for discharging are connected, and when an overvoltage is applied to the switching element, the overvoltage is absorbed by the capacitor via the diode, and after the overvoltage disappears, the positive portion of the overvoltage absorbed by the capacitor is An overvoltage prevention circuit for a switching element, wherein the electric charge is discharged by a Zener diode and a resistor.
