Design of Digital Variable Frequency Power for Grounding Resistance Measurement
摘要
Abstract
Based on the principle of SPWM,this paper discusses how to improve the rate and precision of fre-quency synthesis of variable-frequency power supply by utilizing resources on the chip of SPCE061A and gen-erating waveform data form with advanced language and in lookup-calling form . The experimental results show that the power has high efficiency with good power waveform,which is suitable for grounding resistance measurement.关键词
