The invention provides a storage battery high-efficiency formation incentive charge device which belongs to the technical field of electron. The invention solves the problems that the formation efficiency is low, the environmental pollution is caused easily, and the like. when the storage battery is produced currently. The storage battery high-efficiency formation incentive charge device is used for urging electrolyte in the storage battery; the device comprises a power amplifier circuit which is used for producing plus-minus pulse current and a power supply; a power amplifier driving circuit which is used for driving the power amplifier circuit to produce the plus-minus pulse current is connected between the power amplifier circuit and the anode of the power supply; the power amplifier circuit is connected with a rectifier circuit which is used for adjusting the width and the scope of the plus-minus pulse current produced by driving the power amplifier circuit; the output end of the rectifier circuit is connected with the storage battery. Through a charge container formation after the high frequency plus-minus pulse current is produced to pour the electrolyte into the storage battery assembled by a green plate, the device prolongs the service life of the storage battery, increases the storage battery capacity produced primarily and at the same time reduces the pollution emission.

According to the BUCK amplitude-modulated high-frequency high-voltage electrostatic power supply and the working method thereof, after power frequency rectification filtering, BUCK chopping and high-frequency filtering are adopted, direct-current bus voltage with the amplitude modulated by the BUCK chopping is output, a series resonance inverter circuit composed of an IGBT full bridge, a capacitor and an inductor is connected, the resonance inverter circuit is controlled through pulses to work, and pulse current is output; and meanwhile, the two groups of series resonant inverter circuits work cooperatively, so that the pulse frequency of the pulse current is improved, and the amplitude-adjustable high-frequency high-voltage power supply is obtained. Through combination of the BUCK amplitude modulation technology and the high-frequency power supply technology, the power factor of a traditional silicon controlled rectifier amplitude modulation power supply is improved, the amplitude modulation range is widened, the application scene of the high-frequency power supply is further widened, and the reliability and adaptability of the high-frequency power supply to special working conditions are improved.
