I have built a pure sine inverter using EG8010,Everything is OK but sometimes(usually after connect and disconnect load for several times )despite of "Always on indicator LED" The output PWM go off!
Please help me find out the reason.
Hi,
Yes,It is a 15W Incandescent light bulb,generates small spikes.
No,As I Said It's only 15W.
It's >15A analog power supply. Without load it's 12.8V,Under load:about 12V
Datasheet confess that sometimes need to hard reset after auto disabling SPWM after Current,voltage or temp protection operation, But I connect Ifb and Tfb to GND that disable current and temperature protection and it didn't sole my problem.

What do you mean 2A?I have a H-bridge include 4 IRF840 driving with 2 IR2110.
15W bulb is 220V I connect to H-bridge output.
some TVS diodes solved my problem.4 between S-D of all mosfets and one between input 325VDC(after shunt res)
Also sometimes 8010 hangs up during frequently connect and disconnect load ,An EMI filter solved this problem to.Thank anyway.
