I need to build Three Phase AC Induction Motor Constant V/F drive using pic18F. I want to know 1. Do I need 3x Full-Bridge outputs for driving the AC Induction Motor ? 2. To maintain constant V/F do I need 3 phase feedback voltages or can one feedback sufficient ? - - - Updated - - - I am really sor
hello everyone, 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
Folks, 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 :?: Of course
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.
Hi, Can pic 16F877 drive 3KW AC Motor? If not, What series of pic is most suitable? Need a driver IC(as LM298N)? Zaw
