Abstract

PURPOSE:To enhance the reliability of a circuit by reducing the number of used parts by using a photovoltaic element for the firing circuit of an SCR. CONSTITUTION:When no control input signal is between terminals C and D, a light emitting diode 13 does not emit a light, and a photodiode 11 does not generate photovoltaic power. Accordingly, no gate current will flow to the gate of an SCR1, aNd the SCR1 is not fired. When a control input signal is applied between the terminals C and D, the diode 13 will emit a light, and the photodiode generates photovoltaic power. A gate current will flow to the gate of the SCR1 by the photovoltaic power to fire the SCR1.
