More Information
Summary:The invention discloses a passive direct-current voltage transducer, which consists of a voltage division circuit, an oscillating circuit consisting of a multi-tap high-frequency transformer, and a rectifying circuit, wherein the voltage division circuit is used for dividing input high direct-current voltage, the voltage is converted and isolated through the oscillating circuit consisting of the multi-tap high-frequency transformer and finally the precise rectifying circuit outputs a voltage or current signal in proportion to the input high-voltage direct-current signal. Voltage division signals obtained through the voltage division circuit provide working power for the oscillating circuit consisting of the multi-tap high-frequency transformer. Through accurate signal modulation of the multi-tap high-frequency transformer, not only can the isolation of primary voltage and secondary voltage be effectively realized and can high voltage be prevented from jumping to a low-voltage end and damaging output equipment
