| Abstract |
This paper describes the characteristics of two discrete delta modulated (DOM)
inverters, namely the Asynchronous (ADDM) scheme and the Synchronous (SDDM) inverters. The ADDM scheme operates with asynchronous switching frequency and generates harmonies that spread over a wide range of frequency. The SDDM scheme operates with constant switching frequency and generates harmonies at well defined frequencies that correspond to the switching frequency and its multiples. Both schemes have been implemented using a microprocessor based system and tested. Experimental results are
presented. The advantages and disadvantages of both schemes are discussed. |
