Detailed Documentation
This is a three-phase current hysteresis PWM controlled inverter circuit primarily designed for converting direct current (DC) to alternating current (AC). The circuit employs three half-bridge inverters to independently control each phase output. Three current hysteresis controllers are integrated to precisely regulate the frequency and amplitude of the output waveform. The controller implementation typically involves real-time current error calculation and switching state determination through hysteresis band comparison algorithms. Multiple protection circuits and filter networks are incorporated to ensure circuit stability and reliability, including overcurrent detection routines and output filtering algorithms. Overall, this configuration represents an efficient, stable, and reliable three-phase current inverter system featuring robust digital control implementation with programmable hysteresis bands and protection thresholds.
