Problems solved by technology

Pulse corona discharge desulfurization and denitrification technology needs to generate a steep pulse rising edge (nanosecond level) on the load side. The traditional microsecond pulse power supply can no longer meet this requirement, and requires long-term work. , repetition frequency operation effect, switch life and other characteristics have put forward higher requirements. In the prior art, the common technical problems of high-voltage pulse devices are large power supply and complex structure, which limits its promotion and use.
