DC High Voltage Generator
Product Introduction:
The DC high voltage generator adopts a medium-frequency voltage doubling circuit. The new DC high voltage generator applies PWM pulse width modulation technology and high-power IGBT devices. According to electromagnetic compatibility theory, special shielding, isolation, and grounding measures are adopted. This enables the DC high voltage test to achieve high quality, portability, and the ability to withstand rated voltage discharge without damage. The DC high voltage generator has multiple protection functions, such as: low-voltage overcurrent, lowovervoltage, high-voltage overcurrent, high-voltage overvoltage, zero-position protection, and non-grounding protection. The drive signal fast shutdown protection uses a dedicated sensor at the output end for sampling, with a response time at the nanosecond level. Through nanosecond-level optical isolation elements and nanosecond-level analog switches, the drive signal of the power amplifier circuit is cut off within 2 microseconds, ensuring that the power device is not damaged in the case of output short circuit. It refers to a high-voltage power supply mainly used in insulation and leakage detection. There is no strict distinction between high-voltage power supplies and high-voltage generators. The DC high voltage generator is the first in the industry to adopt a segmented structure, which can be used for both high voltage levels and lower voltage levels while maintaining its accuracy.
