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.

Description

technical field [0001] The invention relates to a high-voltage pulse device, belonging to the technical field of pulse power supplies. Background technique [0002] High-voltage pulse power supply has outstanding advantages such as high output voltage and low energy consumption, and is widely used in environmental protection, medical treatment, military and other fields. In the prior art, nanosecond-level pulse circuits, pulse corona circuits, transformer circuits, half-bridge topological circuits, T-SCC generating circuits, etc. are usually used in order to obtain high-voltage pulse devices. However, in the above circuit, due to the limitation of transformer leakage inductance and other factors, the nanosecond-level pulse power supply generally achieves narrow pulse width through all-solid-state, or boosts the voltage through a pulse transformer, and then compresses the pulse width to nanoseconds through pulse steepening technology. class. Pulse corona discharge desulfuri...
