The high frequency and high voltage pulse is one of the key technologies for the insulation evaluation of inverter-fed motors. Generating, managing, and safeguarding such pulses deviates significantly from traditional high voltage DC and sinusoidal conditions, presenting critical challenges in their creation. Consequently, a high frequency and high voltage pulse generator has been devised, boasting an adjustable edge time ranging from 40 to 500 ns. This generator leverages field programmable gate array technology, achieving clock precision at the nanosecond level. Adopting a half-bridge structure initially, the design advances to a full-bridge topology capable of handling a test capacity of 1 600 pF and yielding a peak-to-peak voltage of 24 kV. Incorporating a meticulously crafted multi-level voltage drop protection algorithm, along with real-time pulse width detection, nanosecond-level pulse control, and various antiinterference measures, ensures the generator′ s reliable operation amidst high-frequency electromagnetic interference. Experimental validation confirms that the generated voltage maintains a pulse width and dead time of no less than 1 μs, with a maximum repetition frequency of 100 kHz. This innovation heralds a groundbreaking platform for comprehensively testing the insulation parameters of inverter-driven motors.
