Abstract
A new design of high-resolution digital controlled AC source with double D/A structure is put forward in this paper. The method dealing with the problem of low D/A refresh-rate is discussed in detail. The substantial ideal of the proposal method is moving the problem in time domain into a memory space domain. With a simple algorithm and a little large size memory, the system can operate properly without increasing the clock frequency of DSP or MCU.
