This is a low-cost DC-HV DC converter built using TL3843 Low-Power Current-Mode PWM Controller from TI. Screw terminal connectors are provided for input and output, onboard LED D1 indicates the input supply. The project provides 200V DC @ 20mA output from 12V DC supply input. DC-HV DC...

The project presented here is a 3 Phase (3Wire) EMI Power line filter which reduces electromagnetic interference and noise conducting in to and out of equipment power lines. These EMI filters can prevent electromagnetic noise of equipment going into the power line and disturb the proper...

This project provides AC voltage zero-cross timing detection and a DC voltage after diode rectification with high accuracy. Possible applications for such circuits are AC motor controllers, AC lamp controllers, AC Dimmer Controllers, Home Appliances. The circuit outputs a zero-cross...

When powering many appliances from a sine wave inverter, the HV DC is converted to AC only to be rectified back to DC in the appliance. This inverter eliminates the SPWM stage and outputs DC only. This DC can be used to power appliances, or as a HV DC source for your SPWM, variable...

Although this power supply design is specific to the Intelligent Power Modules (IPM), the concepts and circuit design may be used for any power supply that requires high voltage output up to 400V DC and 6 A. It is an unregulated power supply, DC output is dependent on AC input.  The...

Nixie tube is an electronic device for displaying numerals or other information using glow discharge. A potential difference is applied between two electrodes in a glass tube containing low-pressure gas. The flow of electric current through the gas makes plasma. This phenomenon is...

This IR remote controlled dimmer works with a triac and in its standard configuration is suitable for light electric heaters and incandescent lamps up to about 1000 watts. The PIC microcontroller used in the project can learn control codes from almost any remote control. Here’s power...

Dimmers provide a way to reduce the power of resistive elements like heaters and light features by changing the waveform of the voltage applied to them. There are different approaches to the development/implementation of dimmers and there are a lot of how-to guides and projects based on...
