Microprocessor controlled PWM inverters for UPS applications

Microprocessor controlled PWM inverters for UPS applications

This thesis describes the implementation of microprocessor controlled single-phase and three-phase inverters for UPS applications. A carrier frequency of 18 kHz is employed in both cases, and the PWM pulses are generated directly by the microprocessor using the regular-sampled symmetric PWM strategy...
