With the EGS002 you can design all sorts of inverters with input voltage, output voltage and power ratings of your choice! For as low as $20, depending on your specs and where you source your components. You would have to build a few components around it to make it into a functional inverter unit.ĭecent high power commercial pure sine wave inverters are very expensive! They range from $120-$400. You can build low power to high power inverter units out of it! Right out of the box, It is not an inverter just yet. The EGS002 is a versatile $3 all-in-one solution for building Pure Sine Wave inverters. Part 3 will show the process behind designing user specific inverter using the EGS002 module and Part 4 on building a better inverter with a 48V input for my off-grid solar panel setup. Part 2 of the video tutorial will show the troubleshooting process and connecting it to a bigger transformer. As far as it goes I was only able to reach 400W with minimal sine wave distortion. Due to unavailability, I was only able to acquire a surplus 500W 12V-220V UPS Transformer. The board was designed to cater a 1kW transformer.

I will reconfigure the board and replace the 7805 regulator with an XL7005A switching regulator and some linear regulators for different rails for the inverter board to work with 80V power sources (12V/24V/48V/72V).īe extra careful with this project as it produces a High Voltage - High Current output.

The current board in this board is limited to a 20VDC input due to the MOSFET driver gate drive source being tied to the Vcc and the 7805 regulator's input voltage limitation.

The one on this project consumes 12W of power without load (a bit mehhh)

The next single coil inductor design is expected to yield a smaller form factor, conversion higher efficiency and lower standby power consumption.

Will implement SMT components to make the board smaller.

I'm currently building a DC & AC Wattmeter SD datalogger for monitoring the data for this project and my future power electronics project.

Will update this tutorial for a more detailed bench test.I'll see if it yields a higher efficiency than the EI core design from this tutorial.

Part 2 of the video will show how to implement a single coil inductor for fast switching, replacing the EI core design used in this project.

Theoretically, sine wave inverters are more efficient than square wave inverters depending on the implementation quality.Aside from being cheap and common, square wave inverters creates that obnoxious humming noises in motors, transformers, mostly on everything you plug to it.Square wave inverters are less efficient and can damage sensitive appliances.As a result square wave and modified square wave were the common and affordable options.A few years back sine wave inverters were extremely expensive ($200-$1000).All our AC appliances were originally designed to run on this waveform. Powerplants use generators that generate a pure sinewave output.Selectable Output Frequency (60Hz/ 50Hz).Undistorted pure sine wave output (with load).Has output voltage feedback (constant AC voltage output).

Transformer can be replaced to work with 110V/220V/230V outputs.

Around $30 was spent to build this project from locally sourced parts. The DIY inverter board can handle up to 1kW (depending the transformer size). Car batteries for powering you home? Build a low cost 12V to 220V (DC-AC) Pure Sine Wave Inverter from scratch! The project is based on the low cost EGS002 SPWM driver board module.
