High-voltage variable-frequency power supply

High-voltage variable-frequency power supplies play a vital role in high-voltage transformer testing. Their core advantage lies in their ability to flexibly adjust the frequency and amplitude of the output voltage. Their compact size and flexible operation make them suitable for high-voltage transformer testing and a viable alternative to traditional generator sets.
