Abstract

The invention discloses a high voltage static generator, which is characterized by comprising a power supply control circuit, a rectification voltage stabilizing circuit, a high-frequency converting circuit, a boosting rectification circuit, an overload alarming protective circuit and an output measuring circuit. A 220V alternative-current municipal power is converted to a high-frequency pulse power source through the power supply control circuit, the rectification voltage stabilizing circuit and the high-frequency converting circuit, and then the high-frequency pulse power source is converted to a direct-current high-voltage static power to be outputted to a load through the boosting rectification circuit. The high voltage static generator has the characteristics of simplicity and clarity in circuits, continuity and adjustability of voltage, automatic protection and alarming for overload, safety and reliability in use and the like. The high voltage static generator is suitable for static spray coating, static seed treatment, static flocking and the like.
