FIXED VOLTAGE POWER SYSTEM WITH A SWITCHING

摘要

The system consists of an oscillating circuit which oscillates to output reference frequency, an inverter which inverts the phase of the output voltage of a voltage comparing unit, a switching unit which swtichs by the output voltage from the inverter, an inverter which converts the phase of output voltage from the inverter, a switching unit which controls the voltage from a trans former, a diode which rectifies half wave of the output voltage from the trans former, a variable resistor which controls the level of the output voltage of the diode, a zener diode which compares the voltage at a variable resistor with a zener voltage, and a voltage comparing unit which controls the switching unit by outputting a control voltage.
