Abstract

PURPOSE:To obtain economical great current base drive circuit, by connecting the transformer and the rectifying circuit to the base and emitter circuit of the transistor Tr in opposite direction so that no current flows in the rectifying circuit during the base drive of Tr. CONSTITUTION:The output VOSC of the high frequency oscillator 1 oscillates continuous rectangular waves, and when the signal SIG controlling Tr 7 at time t0 is turned on, a signal is fed to the base of Tr 7 with Tr 3, 4, transformer 10, and rectifier 11. When the signal SIG is 0 at time t1, the signal VOFF is produced from the one shot generator 13 and flows the current of -IB in opposite direction to the base of Tr 7 via Tr 14, transformer 17, and rectifier 18. During the period at time t0 to t1, the number of rectifiers is selected so that the voltage drop of the rectifiers 18 is greater than the voltage between the base and emitter of Tr 7 to avoid the current from being flowed to the rectifier. Next, at time t2 to t3, the carrier storage of Tr 7 is discharged and -IB is decreased. Thus, the turn off time of Tr 7 is reduced, resulting in obtaining economical great current base drive circuit.
