Abstract
PURPOSE: To reduce the power capacity of a resistance to lower the cost price for the circuit constitution by inserting the start resistance between the base of series control transistor Tr and the emitter of error detection transistor Tr.
CONSTITUTION: Series control Tr1 and error Tr6 which detects fluctuation of the output voltage to control the conduction degree of Tr1 are provided between unstable power sources 14 and 14' and loads 12 and 13 respectively, and reference voltage element 7 is connected to the emitter of Tr6, and resistance 15 is connected between the emitter of Tr6 and the base of Tr1, thereby constituting a regulated power supply circuit. At the instant of power supply, Tr1 is not turned on yet, and the base current is flowed through start resistances 15 and 8. When the base current is flowed, the collector current of Tr1 is flowed to turn on Tr1. When the heater of the CRT of the TV receiver of a load is heated and the resistance is increased to enter a normal operation, the current flowed to resistance 15 is smaller than that at the power supply time, and reduction components become the emitter current of error amplification Tr9, and degradation of control capability for stabilization is reduced.
