Product Overview
The portable variable frequency resonance step-up device for cables utilizes the adjustment of power frequency to achieve resonance between the reactor and the tested capacitor. This results in high voltage and high current on the test item, representing a new method and trend in high-voltage testing. It has been widely applied both domestically and internationally.
Variable frequency resonance boosting device utilizes a dedicatedThe SPWM digital waveform generator chip features a 16-bit frequency resolution, achieving a frequency fineness of 0.1Hz between 20 to 300Hz. It utilizes an orthogonal asynchronous fixed carrier modulation method to ensure excellent waveform output across the entire frequency range. The power section incorporates advanced IPM modules, ensuring stability and safety of the instrument with minimal weight.

The变频 resonance step-up unit consists of a frequency-modulated voltage regulator, excitation transformer, reactor, and capacitor voltage divider.
