Abstract

PURPOSE: To reduce mean base-driving current by driving a base by a ON-OFF current, which is OFF within accumulation time, at the time of the conducting of the transistor.
CONSTITUTION: When the driving signal of input terminal TM of base driver circuit 1 becomes high in level, its rise is differentiated D1 and the signal passes through gate circuit G1; monostable multivibrator circuit MM1 output pulses which are OFF for T1 determined by time constants C1 and R1, and monostable multivibrator MM2 outputs pulses which are OFF for T2 determined by time constants C2 and R2. Then, an oscillation output, which is ON and OFF alternatively for T1 and T2, driven by the driving signal is obtained at output Q1 of MM1 and this signal is amplified A1; and transistor 2 to be driven conducts at T1, and collector current Ic flows to main circuit line 3, but the output of A1 becomes zero at T2 and base current IB does not flow. Although IB is intermitted, T2 is set within the accumulation time of Tr2, so that Ic will flow continuously.
