ApplicationNo./PatentNo.: 200620 137723
The invention relates to a repairing instrument for repairing a storage battery by using high-frequency pulses. The repair circuit of the repair instrument includes an oscillation circuit, and a high-frequency signal amplification circuit and a power amplification circuit are sequentially connected in series after the oscillation circuit. The high-frequency signal amplification circuit includes a voltage amplification circuit and a current amplification circuit. The repair circuit is provided with a first power supply circuit and a second power supply circuit, wherein the first power supply circuit supplies power to the oscillation circuit and the high-frequency signal amplification circuit, and the second power supply circuit supplies power to the power amplification circuit. The first power supply circuit consists of storage battery and voltage stabilizing circuit, and the power supply of the second power supply circuit is provided by 220V commercial power, which outputs DC voltage after voltage transformation and rectification. The repair circuit can generate high-power pulse signals to repair the battery quickly.
