Title: Gate driver for self-extinguishing element and gate driver for power converter
Inventor: OKAMATSU SHIGETOSHI
IPC: H02M1/08
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive gate driver in which a DC power supply dedicated for charging of capacitor is not employed. SOLUTION: An on/off capacitor C4 is operable at the time of turn on and turn off. The gate junction (G.K) of a self-extinguishing GTO, the on/off capacitor C4, a DC power supply VONH for turn on, a current limiting impedance IMP, and a turn on switch Tr3 being closed upon turn on constitute a closed circuit for forward current supply. The closed circuit supplies a forward current to the gate junction (G.K) and charges the on/off capacitor C4. The gate junction (G-K), the on/off capacitor C4 and a turn off switch Tr4 being closed upon turn off constitute a closed circuit for reverse current supply. The on/off capacitor C4 is discharged through the closed circuit which also supplies a reverse current to the gate junction (G.K).  The power supply for charging the on/off capacitor C4 is not a power supply dedicated for charging but the DC power supply VONH for turn on which is essential to the closed circuit for forward current supply.
