Hello All Forum members.
on Chinese forums i found this complete project of Sine wave inverter built around TDS2285.

Interesting way of pause (dead-time) management. Due to it in this circuit it is possible to use as pwm-generator that is even attiny13.
 
thanks for the circuit, but the TDS2285 IC is an uncommon IC and not available in the market, so this project will be of theoretical interest only
 

TDS2285 IC is microcontrller or not? TDS2285 IC only sold in china? Where can buy this IC?
 

This TDS2285 chip needs "crutches" in the manner of external chains for dead-time management so this is not ingenious choice for sinewave inverter devices. Better use MCU like AT90PWM3.

Click to expand...

AT90 with PWM is good idea, do you have schema or example worked? which components need else?
 

This only gedanken prototype. Possible will be useful to somebody in separate detail but not moreover.
Apropos ATTiny45 could be useful too. That is identified as "cheaply and angrily" )
