![]() But if no load is connected, the circuit works fine and IC doesn't shutdown. I tried to connect a 20watt load for a test, immediately I connect it, egs002 will shutdown and light blinks 4 times which means undervoltage protection (as stated in datasheet). I powered my circuit and connected my scope, it worked fine, I adjusted 10k pot from VFB, to get 200v ac output which worked fine. FanCtl, TFB were left open (not connected) I connected the Ho1, ho2, Lo1, Lo2, vs1 and vs2 to their respective pins on d egs002 board, IFB is grounded and VFB is connected to an 12v additional widing of d transformer which is rectified using 4 1N4007 diodes and adjusted with a 10k variable resistor.ġ2v and 5v were connected to their respective pins on the egs002 board. I believe this bridge should give me at least 100watt power. EG8010 is a digital, function very well bring their own dead-time control of pure sine wave inverter generator chip, used in two-stage DC-DC-AC power conversion structure or single-stage DC-AC power frequency transformer Boost architecture, an external 12MHz crystal oscillator, to achieve high precision, and harmonic distortion is very small. I rewind this transformer to 0-7.5/220v to use for my egs002 inverter which I believe it should give me at least 500watt on 12v system.įor a test, I used 1 fet per bridge, making a total of 4 fets, I used irf3205 and 4.7ohm resistor with 1N4148 diode at each gate, with 10k resistor from each gate-source as stated in d datasheet. I savaged a transformer from an old ups, the transformer is 15-0-15/220v which is meant for a 24vDC 1.2kv ups. I started a Pure Sine Wave inverter project which I am to use egs002 for this purpose.
