This product is mainly composed of variable frequency control power supply, excitation transformer, reactor, and capacitor voltage divider. Among them, the variable frequency control power supply adopts imported special SPWM digital waveform generation chip, the frequency resolution is 16 bits, and the frequency fineness can reach 0.1Hz at 20～300Hz. At the same time, the orthogonal non-synchronous fixed carrier modulation method is adopted to ensure the The output waveform is good in the entire frequency range; the power part adopts advanced IPM module to ensure the stability and safety of the instrument.
