Power supply with Z2C

Power supply with Z2C tubes are designed specifically to provide power supply voltage to the EL-34 tube amplifier push-pull in the previous article. Power supply with Z2C tube to tube power amplifier is made with a tube rectifier Z2C. Just as the power supply for power amplifier tube earlier, power supply also uses a filter 3 levels with kapsitor electrolyte. Circuit power supply with tube rectifier Z2C can give +210 VDC output voltage. A complete range of power supply for power amplifier tube can be seen in thethe following figure .

Z2C on the rectifier tube in power supply with tube above require a supply voltage for the filaments taken from the other side of the transformer secondary. Power supply with Z2C tube is a power supply that dapt used as a substitute power supply for power amplifier tubes with a diode in previous articles.

Power Supply EL-34

Power supply for EL-34 tube is specially designed for the purposes of power supply at the push-pull amplifier with EL-34 tube as in article 35 Watt Tube Power Amplifier Push Pull before. Power supply for EL-34 tube amplifier is made with transformers CT and 2 pieces diode as rectifier. Mechanical filters are applied in the power supply uses 3 levels. Power supply for tube power amplifier can deliver output voltages +220 VDC. Circuit details can be seen in the following figure.

The above power supply circuit has a high output voltage so that need to be considered in the manufacture and perakitanya because electricity can tesengat (stun). Power Supply For Tube Power Amplifier With Diode EL-34 was created specifically for the power amplifier tube push pull EL-34.

UPS Power Supply

UPS Power Supply For in this article is the power supply that is often applied in the system electronics which adopted the principle of the UPS . By adopting the principle of the UPS , the circuit power supply is still able to work even though there is no AC voltage source. For UPS Power Supply circuit consists of lowering the voltage, rectifier, charger , batery and regulators . The technique is applied from UPS on the power supply is the use of batery and charger is connected dengang direct coupling with a series diode. For more details can be seen with the following image.

The rectifier in series UPS Power Supply For this to function also as a charger via D1. D3 function is to drain-source voltage of the rectifier to the series regulator when there is an AC voltage source. D2 serves to drain the batery when the source voltage from AC voltage source does not exist. batery configuration and diode D1, D2 and D3 is adopted from the UPS system . may be useful and can provide inspiration on all in making backups on the system power supply voltage.

10A High Current variable power supply

Power supply has 10A maximum current and output voltage can be set from 2 - 36VDC. Power supply circuit is quite simple, which is composed of the rectifier, voltage regulator and power regulator. Power regulator circuit High Current Variable Power Supply 10A uses the Q3 and Q4 are arranged Darlington and serves as a power regulator drivers Q5 and Q6. While the voltage regulator circuit is VR1 which serves as a variable voltage divider and Q1 and Q2 are arranged as a controller driver Darlington power regulator with variable reference voltage divider VR1.

In a series of High Current Variable Power Supply 10A 10A above have been completed as a current-limiting fuse. and to monitor the current flowing with ampere meter and volt meter to monitor the output voltage of the circuit.

Simple Power Supply with 2 transistors

Power Supply in this post is using a regulator which is composed of 2 pieces of NPN transistor. A transistor acts as a power regulator and a transistor again serves as a controller output voltage. Power Supply has an adjustable output with a range of 6-12 VDC. The part that serves as a power regulator is Q1 TIP31. Then the controller output voltage is a voltage divider composed of R3, R4, VR1 and R2 provide bias to the base of Q2 to control the power regulator Q1. In a series of power supply is mounted 5.1 V zener diode which serves to make the minimum limit the output voltage with Q2.

Power Supply With transistor circuit is quite simple and can be made with the PCB holes, so for those who want to try to directly mempraktikannya. May the power supply circuit can be useful for readers, especially for friends who need a power supply circuit with the regulator transistor.

Variable Switching Regulator Circuits

Switching Regulator Variable L4970 is supplying current to a maximum of 10A with an adjustable output voltage from 0-25 VDC. Switching Regulator Variable L4970 series is built with the main component as a Switching Regulator IC L4970 her. Switching Regulator Variable L4970 series include not complicated to make his own, which need to be considered is the IC L4970 require sufficient cooling to operate in an optimal and durable. Switching Regulator Variable Series L4970 complete picture can be seen below.

Variable Switching Regulator

Output Voltage Switching Regulator Variable L4970 series can be in control by adjusting potentiometer 18KOhm.
