Description

technical field [0001] The invention belongs to the technical field of power supplies, and in particular relates to a power supply device for a high-voltage electrostatic defogger using a three-phase L-C constant current source with a six-terminal network L-C resonant converter. Background technique [0002] The traditional single-phase L-C constant current source high-voltage DC power supply in the prior art has the advantages of constant current output characteristics, high power factor, continuous and reliable operation, etc., and has been used in many special dust removal environments, such as electric demisting devices and electric coking devices. be widely used. Its shortcomings are: since the constant current source high-voltage DC power supply adopts single-phase power supply, it is easy to cause electric field discharge, the corona power is small, and the efficiency of dust removal and coke capture is low. It is easy to cause grid imbalance and affect the security ...
