Switching-power-supply
This low-voltage, high-current output switching power supply operates from a 220 VAC input. In this circuit, an ST2 diac relaxation oscillator, along with Q3, C1, and the diac, initiates the conduction of the output switching transistor Q1. The on-time of...
Regulator circuit silicon resistor formed
The simple voltage regulator circuit consists of a silicon regulator and a resistor. It is designed to rectify and filter DC voltage, as illustrated in the accompanying figure. The voltage regulator is connected in parallel with the load, and the...
WSl57 + 5V 1.6A precision switching power supply circuit comprising
The circuit incorporates an optical coupler (CNY75A) and an adjustable precision shunt regulator (TL431). It includes current limiting resistors R3, R4, and R5 for the sampling resistor. As the output voltage (Uo) varies, the voltage across the sampling resistor and...
Regulated 12 Volt Supply
This circuit utilizes a 13-volt zener diode (D2) for voltage regulation. Approximately 0.7 volts are dropped across the base-emitter junction of the transistors, resulting in a higher current output of 12.3 volts. The circuit is capable of supplying loads up...
how does power supply regulate its
Most power supplies regulate either their output voltage or current at a constant level, depending on the load resistance relative to the power supply's output voltage and current settings. This can be summarized as follows: To accomplish this, most power...

Variable Voltage Regulation
Controlling the output voltage from a regulator can be made variable in three ways:
1. Using a fixed reference zener diode to increase the output by the value of the zener
2. A variable resistor for variable output, note that...
