- Abstract:
- According to the characteristic of synchronous reference sinusoidal circuit of Dynamic Voltage Restorer (DVR),its principle scheme was confirmed. Based on the method and program of Proteus product design,the theory calculation results were validated about analog and digital circuit of scheme by software simulating. Design idea that “putting analog devices into bus” was implemented in variable gain amplifier adopting I2C bus interface AD5241 by MCU programming. Finally,simulating curves of input,output and feedback voltage waveforms with harmonic and fluctuation were provided. It proves that the circuit is up to the design requirements
