    摘要: A pulse charging for a battery includes multi-stage voltage conversion. At first stage, an input voltage from a power supply is divided into a plurality of intermediate voltages. At second stage, one or more of the plurality of intermediate voltage are further down converted to generate one or more portions of a charging pulse to be applied to the battery. The down conversion of the input voltage to the output voltage is accompanied by increase in charging current that is applied to the battery. The higher charging current applied to the battery results in fast charging of the battery. Also, the described multi-stage voltage conversion circuitry has high efficiency which alleviates problem of heat dissipation associated with the voltage conversion for charging of the battery.
