Abstract :
A principle of integral control of the output voltage in PWM voltage-source inverters is described. The proposed approach is a modification of the known delta modulation technique, and consists in closed-loop control of angle-domain integrals of switching signals for individual phases of the inverter. Integrals of the corresponding modulating functions serve as reference signals. Integral control has several superior features in comparison with traditional PWM techniques. Theoretical considerations, computer simulations, and experimental results are presented
