Power pulse generator for electrostatic precipitators

In order to overcome disadvantages of pulse generator for electrostatic precipitators (ESP), such as pulse stretching, residual voltage accumulation of capacitors and oscillating voltage of ESP, an appropriate solution with an auxiliary switch inversely connected to the charging diode in parallel is put forward. This article analyzes the principle of the pulse generator for ESP at length, and provides the theory of the selection of critical parameters. The simulation analysis and low-voltage experimental results confirm the validity of the solution. The improvement of pulse generator for ESP is conductive to further improve the collection efficiency and energy utilization.
