DC parallel stabilized power supply circuit

DC parallel stabilized power supply circuit

Shown is a DC parallel regulated power supply circuit used in the radio circuit . The AC 220 V voltage is stepped down by the transformer and outputs
8V AC low voltage. The 8V AC voltage outputs about 11 V DC through the bridge rectifier circuit, and then is filtered by CT. R , Ds voltage stabilization, C2 filtering and outputting
6V stabilized DC . Two electrolytic capacitors are used in the circuit for smoothing filtering.
    Although the power supply circuit using a Zener diode for voltage stabilization is simple, its biggest disadvantage is that the Zener diode
still consumes current when the load is powered off. The smaller the load current, the greater the current flowing through the Zener diode, because this The sum of the two currents is equal to a constant. Therefore, this regulated
power supply is only suitable for situations where the load current is small and changes little.
