i want to know that is there an h-bridge inverter module exists?
i have my final year project which is variable frequency drive (speed control of single phase ac induction motor).
i have generated spwm signals using pic mcu through which i can achieve variable frequency. however, i am stuck with the inverter and now want to use a

it is possible to control industrial ac servo motor(with drive) using pic microcontroller, servo drive accepts step and direction signals

You need sine wave directly from pic, here
or you need SPWM (to make inverter), here

I?d like to drive an H-bridge with 60Hz square waves with large dead time. This is for a DC to AC wonder. As long as pic's clock is no faster than 13.1Mhz, it should be possible to generate such slow waveform with ECCP. Right :?:

I want to make a dimmer cum fan regulator circuit. For driving AC load (incandescent bulb and FAN) TRIAC gate firing signal generation will be through pic microcontroller and it is almost complete. Now I need to design the load driver part. Generally TRIAC is used to drive the load. I also want to use it. For isolation I saw uses of MOC30xx (...)

Hi I need some help,
I want to transform, in my circuit, a double inverter relay (too big), in an electronic control.
The only way I've found, is 4 triacs (one in each wire the relay was commuting) with their trigger controlled by a microcontroller.
The circuit is driven by a reaction of an accelerometer which inform the chip (with an impulsion)

A pic with an LCD driver like the 16F917 may be required. LCDs are AC not DC devices.

pic by itself can drive nothing, or next to nothing ..
If, however, pic controls a relay (solid state relay), SCR or Trac, it can drive almost any AC motor ..
