    [SOLVED] Pic 16f876a Pure Sinewave inverter

    Re: tz2l9 sorry could i ask , i use hi-tech C 9.80 or 9.83 could no be compile success , may i ask which compiler u are using . i was error that #include <16F876A.h> and if i change to htc.h also wont work . may i know u are using hi-tech OR CCS ????

    I got a question In H-bridge connect a resistor from gate to source,pls have a look

    I have between two circuit one is resistor no connected gate to source and resistor connected gate source.a May i know what is the main purpose between this two circuit . i like to know , because i have design my sine wave inverted , i doubt in this consideration . hope someone can clearly...

    igbt goes short circuit

    this reason is very useful between gate to source have to put a resistor , i also facing a problem with design inverter i have a write a programming , tested in simulation for one button on/off , but my cases i withouth put any resistor to gate to source then my circuit sometime depend on luck...

    IR2110 H-Bridge Inverter for Induction Heater

    i find some error for u design...in decoupling capacitor connection ...but just very small error....for the voltage waveform a bit reflected ..just give u observed the waveform. i dontknow is software problem or i understanding wrong..maybe i should try in real life practical.......i use ur...
