This paper presents a comparative study on the performance of two discrete delta modulation (DDM) schemes for DC-AC power conversion, namely the asynchronous (ADDM) scheme and the synchronous (SDDM) scheme. The ADDM scheme operates with asynchronous switching frequency and generates harmonics that spread over a wide range of frequency.

A semi two-stage DC-AC power conversion system composed of a Boost DC/DC converter and a novel dual-input inverter is presented in this paper. The low voltage DC source and the output of the Boost DC/DC converter are used as the low-voltage and high-voltage DC input ports, respectively, of the dual-input inverter.

30 kW electrical power conversion system is developed for a variable speed wind turbine system. In the wind energy conversion system (WECS) a synchronous generator converts the mechanical energy into electrical energy. As the voltage and frequency of generator output vary along the wind speed change, a DC-DC boosting chopper is utilized to maintain ...

Microprocessor-based random PWM schemes for DC-AC power conversion
IEEE Transactions on Power Electronics, 1997This paper compares and evaluates two classes of microprocessor-based random PWM (RPWM) real-time generation schemes for DC-AC power conversion. The practical performance of the RPWM schemes based on mathematical and logical approaches are examined. The proposed schemes exhibit excellent EMC and harmonic content with all low and high order harmonics ...
