Abstract: A charger with output voltage compensation includes an AC/DC circuit, an output interface, a charge controller, and a compensator. The AC/DC circuit converts an AC source into a DC source. The voltage of the DC source is elevated by a transformer and used to charge a battery via the output interface. The charge controller can further increase the voltage of the output interface in order to accelerate battery charging. The compensator compensates the voltage wasted by the circuit. Therefore, the invention can overcome energy waste caused by the internal resistance in the circuit, achieving satisfactory charging effects.

Abstract: A two-step charger includes an AC/DC power supply, a transformer, a compensator, a controller, a comparator and an isolating controller. The comparator detects whether a battery is connected to the transformer. If so, a command voltage of the charger is set at a high level. Since the battery voltage is lower than the command voltage, the controller orders the compensator to send out a compensating current. The current entering the primary side of the transformer is increased to promote the output current from the secondary side of the transformer. Once the comparator detects that the battery reaches as high as the charger, the command voltage is adjusted to a low level. The controller orders the compensator to stop outputting the compensating current. Therefore, a larger current can speed up battery charging. Once the battery is fully charged, the charging voltage is lowered to avoid high temperature.
Abstract translation: 两步充电器包括AC / DC电源，变压器，补偿器，控制器，比较器和隔离控制器。 比较器检测电池是否连接到变压器。 如果是这样，则充电器的指令电压被设定为高电平。 由于电池电压低于指令电压，控制器命令补偿器发出补偿电流。 增加进入变压器初级侧的电流，以提高变压器次级侧的输出电流。 一旦比较器检测到电池达到与充电器一样高的电压，则将指令电压调整到低电平。 控制器命令补偿器停止输出补偿电流。 因此，较大的电流可以加速电池充电。 一旦电池充满电，充电电压降低以避免高温。
