The frequency conversion series resonance withstand voltage test device applies the principle of series parallel resonance. By adjusting the output frequency of the frequency conversion controller, the inductance L of the reactor in the circuit and the capacitance C of the test sample resonate, and the resonant voltage is the voltage applied to the test sample. Variable frequency series resonance provides power supply through a frequency modulation controller. The test voltage is initially boosted by an excitation transformer, and high voltage is applied to the reactor L and the test sample CX. By changing the output frequency of the frequency modulation controller, the circuit is in series resonance state; The resonant frequency of the circuit depends on the capacitance CX of the test sample and the inductance L of the reactor. Adjust the output voltage of the variable frequency controller to achieve the required voltage value on the high voltage of the variable frequency series resonant withstand voltage test device.
