According to the accurate sampling needs of the power voltage, designs a kind of DC bus voltage detection circuit that applies to the high frequency power supply in electrostatic precipitation. Based on the introduction of the principle of high precision linear light-coupler HCNR201 works, the paper designs the new-style DC bus voltage detection circuit of high frequency power supply, and uses sampling resistor divider way to realize the voltage detection, and by using the high precision light-coupler HCNR201 to realize the electrical isolation of the high voltage side and the low voltage side. The paper presents the design of main circuit of high frequency power supply, the experiment results which based on the circuit and the corresponding curve fitting analysis are given. The experiment shows that the circuit with high accuracy and linearitv can be widely used in high voltage detection occasions.
