The Design of the Signal Generator Circuit for Single-Phase Industrial Frequency Power Based on XC2C64A

The paper mainly introduces the new signal generator circuit of industrial frequency power based on XC2C64A, which focus all digital circuit in a CPLD chip, making simple structure and convenient debugging. And the general diagram, design idea, the benchmark waveform signal oscillating circuit, frequency synthesis circuit, phase synthesis circuit and D/A transformation circuit are given in the paper. The phase and frequency of the circuits are simulated.
