Abstract
PURPOSE: To make stable the output voltage with a simple constitution, by rectifying the AC power supply with the rectifying circuit, connecting in series the first and the second control means between the output and load, comparing and controlling the output of the control with the comparison circuit for the specified value.
CONSTITUTION: The output of the first rectifying circuit 7 is fed to the input terminal of the first control circuit 8, and the full wave rectifying output voltage of the second rectifier 15 is fed to the input terminal of the saw tooth wave generating circuit 17. The saw tooth voltage of the circuit 17 is fed to the input of the first comparison amplifier 14 and set to the reference value. The output voltage from the circuit 8 is compared with the reference value at the circuit 14, and when it decreases or increases from the specified value, the variation controls the circuit 8 and the output voltage is returned to the specified value for compensation. The output of the circuit 8 is fed to the second control circuit 9, and the output of the circuit 9 is fed to the voltage dividing resistors 11W13 and the load 10. The voltage divided with the resistors 11W13 is fed to the second comparison amplifier 18 and it is compared with the reference voltage of the circuit 18. The difference is fed to the circuit 9 to compensate the variation of the output voltage.
