DIY 1000W Inverter 12V /24V DC to 220VAC with EGS002 (low power frequency transformer)

Egs002 is a Board Module for building pure sine wave inverters, this module uses the eg8010 microcontroller ic as a sine wave generator, this ic is used in many manufacturers of pure sine wave inverters which are quite popular. with inverter power ranging from 300w to over 10,000 watts net, with this module we can build Pure Sine Wave inverters at low prices with the same wave output. The schematic Inverter 12V /24V DC to 220VAC with EGS002 (low power frequency transformer) same as the video in this post:

 The Low-Frequency EGS002 Inverter  has the following advantages:

-The circuit is compact, does not require a High Volt DC circuit like the High Freq type inverter

-Durable/durable in shock loads, especially induction loads (dynamo/motor) because the dynamo starting current/initial current is very high applied to the inverter will be resistant to the first transformer not directly to the MOSFET, in contrast to high freq inverters which will receive direct starting load on the H-bridge MOSFET and there is a vulnerable level if the MOSFET power is smaller / weaker for high-freq type inverters.

-Resistant to high distortion/noise loads, the distortion load has a ripple voltage or very high voltage even though it is only microseconds/milliseconds above the voltage that the MOSFET can experience, but the high ripple voltage will be dampened on the transformer, so it is not directly experienced by MOSFET like the high freq inverter type without a good output filter.

The low freq inverter type has an efficiency range of 70-85% or wider than the high-freq inverter type, which is 90-96%, but if the two inverters are loaded at peak load, the efficiency is almost the same in the 80-85% range.
