Problems solved by technology

[0002] Conventional chargers use transformers, rectifiers, current limiters, batteries and other units to charge the battery with 220V AC. During the charging process, the transformers, current limiters and other units will consume additional power, which will reduce the power utilization of the charger; Conventional chargers use inductive load characteristics and have a low power factor. If the charger is used excessively, it will seriously affect the quality of the AC power supply and cause a large amount of reactive power loss. When the conventional charger is used in an exposed environment, The battery casing, all components, connecting wires and other metal parts may be charged, and it is very unsafe to use

Abstract

The invention relates to a charger and a construction method thereof. The conventional charger employs inductive load characteristics, and is lower in power factor; if the charger is used excessively, the quality of an alternating current power supply can be influenced seriously; reactive loss of the alternating current power supply is caused greatly; and a battery case, all components, connecting wires and other metal parts are electrified possibly when the charger is used in an exposed environment, so that the use is very unsafe. According to the construction method of the charger, a battery is charged when a capacitor is charged in an alternating current circuit. The charger can reduce the reactive loss of the power supply and manufacturing cost, saves electric energy, and can be used safely in any environment.
