IPC: H02P7/288
Filed: 1986-07-11
Abstract: PURPOSE:To set both a operating current and operating time optionally by connecting a time constant circuit comprising a capacitor and a variable resistor to a base of a switching transistor (TR) controlling the application of a gate voltage to a thyristor. CONSTITUTION:A TR 1 is a transistor (power TR) inserted in series with the titled circuit and a TR 2 is a switching TR controlling the gate of a thyristor SCR.
