The is a highly efficient 8-bit microcontroller from Microchip Technology that has become a staple for hobbyists and engineers designing low-cost, high-performance inverter circuits . Its specialized "Enhanced Capture, Compare, PWM" (ECCP) module makes it uniquely suited for generating the complex pulse-width modulation (PWM) signals required to convert DC power into AC. Key Features for Inverter Design
Prevents "shoot-through" by ensuring one MOSFET is fully off before the next turns on. pic16f716 inverter circuit
The raw output from the H-Bridge is a high-frequency square wave (SPWM). To turn it into a 50Hz sine wave: The is a highly efficient 8-bit microcontroller from
CCP1CON = 0x8E; // Half-Bridge mode, PWM enabled, P1A active high, P1B active high PWM1CON = 0x15; // Dead time = (0x15 * Tosc * Prescale) ~ 1us The raw output from the H-Bridge is a
void main(void) // 1. Configure I/O TRISC = 0x00; // PWM outputs TRISB = 0x02; // RB1 as analog input for feedback (AN1) ANSEL = 0x02; // AN1 is analog
This necessitates a . The IR2110 or IR2104 are popular choices.
Supports single, half-bridge, and full-bridge (H-bridge) output modes, allowing it to drive MOSFETs directly with programmable dead-band delays to prevent short circuits.
