Variable High Voltage Power Supply 0-330VDC
Variable high voltage power supply 0-330V can provide output voltage can be set for volts up to 330 volts DC. The maximum current that can be provided by the circuit’s power supply is 100 mA. variable high voltage power supply 0-330V use transformers 1: 1, which means there is no lowering Fator voltage (step-down) or riser voltage (step-up) so that the fixed output voltage of 220 volts AC. Function transformers 1: 1 This is as an insulator between the AC network PLN with an electric power supply network. The variable voltage regulator circuit variable high voltage power supply 0-330V using FET transistor T2 and T1 BC547 BUZ326. To make a variable high voltage power supply 0-330V can be seen as the following circuit scheme.
Circuit Of Variable High Voltage Power Supply 0-330VDC
The circuit of variable high voltage power supply 0-330V in the image above consists of the following sections:
Isolator, this section serves to isolate the electricity grid between the grid with power lines high voltage power supply circuit. The isolator section using isolator transformers 1: 1 so that the output remains 220 volts AC.
Rectifier, this section serves to convert the 220V AC voltage into a DC voltage of 320 volts. To convert AC voltage into DC voltage on a high voltage power supply circuit of this variable is used diode bridge D1 and electrolytic capacitors C1 150 uF / 400V.
Voltage regulators, voltage regulator circuit serve to regulate the output voltage of the power supply voltage is higher than 0 volts DC to 330 volts DC with a maximum current capacity of 100 mA. It was built by the configuration transistor BC547 T2 and T1-type FET BUZ326. To set the output voltage of the variable power supply circuit high voltage can be done by adjusting the lever potentiometer R3 500KOhm.
Raising Output Currents Variable High Voltage Power Supply 0-330VDC
Components that must be replaced if it wants to increase the capacity of larger currents are:
- Transformer TR1
- Diodes D1
- And transistor T1
TR1, D1 and T1 can be replaced with a capacity larger to increase the current output variable high voltage power supply 0-330V this.
