High Voltage, Low Current Power Supply (2000VDC from 15VDC)

High Voltage, Low Current Power Supply (2000VDC from 15VDC)
This is a high voltage, low current power supply capable to deliver 2000VDC output from 15VDC input voltage. It uses the combination of simple step-up transformer and Cockroft-Walton voltage multiplier circuit. Power supply with very high output voltage is a very useful source that can be effectively used in many applications like biasing of gas-discharge tubes and radiation detectors, etc. Such a power supply could also be used for protection of property by charging of fences. Here the current

120 V to 12KV High Voltage Converter

120 V to 12KV High Voltage Converter
Here is the schematic diagram of 120 V to 12KV power supply, or you may call it high voltage generator or 120V to 12KV converter. This circuit produce very high output voltage that is about 12K volt with very small current of about 5 microAmpere. Two SCRs form two pulse generator circuits. The two SCRs discharge a 0.047uF a 400v capacitor through a xenon lamp trigger coil at 120 times a second. (more…)

Simple 400V DC Power Supply

Simple 400V DC Power Supply
This is a very simple 400V DC power supply circuit diagram, or, it may called as 230VAC to 400VDC converter. The working principle of this circuit diagram is very simple. You already knew the working principle of a bridge rectifier. This circuit is same as bridge rectifier and the working principle is also same. The fuse is used to protect the circuit, if the current is greater than 1 A. (more…)
