Abstract
The invention relates to a charger for charging a storage battery. The charger is characterized in that a high-frequency transformer, two low-frequency capacitors and a high-frequency medium polyethylene capacitor are arranged at the front end of a circuit board in an outer casing. Three cooling fins are arranged in the middle of the circuit board, wherein, one cooling fin is provided with large-current high-frequency rectifier diodes, and the other two cooling fins are provided with high-power and high-back-pressure field-effect transistors. Two high-power contactless relays and frequency modulation and pulse width modulation drivers with constant voltages and currents are arranged among the cooling fins respectively. Two high-frequency output electrolytic capacitors are arranged in front of a fan on the tail portion of the circuit board. A power switch, indicator lights, cooling holes and a power line are arranged at one end of the outer casing surface; a fan cover and positive and negative power line clamps are arranged at the other end; cooling holes are arranged on two sides; and a handle is arranged on the upper portion of the outer casing. The charger for charging the storage battery has the advantages of being good in working stability, high in anti-interference performances, small in heating quantity, high in current output power and high in output accuracy and applicable to the charging of devices of large agricultural machinery, vehicles and marine engines which need storage batteries to start.
