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。

Abstract: A power supply used to convert an input voltage into an output voltage, and the power supply includes an input detection circuit, a conversion circuit, a detection circuit, and a controller. The input detection circuit provides a power good signal or a power fail signal according to the input voltage. The conversion circuit converts the input voltage into an output voltage, and the detection circuit detects the output voltage according to the power good signal to accordingly provide an output feedback signal with a first feedback value. The controller stabilizes a voltage level of the output voltage according to the first feedback value. The detection circuit self-adjusts a feedback condition according to the power fail signal, and correspondingly adjusts the output feedback signal to a second feedback value according to the feedback condition. The controller reduces the voltage level of the output voltage according to the second feedback value.

Abstract: A power conversion apparatus with oscillation reduction control supplies power to a load through an output end. The power conversion apparatus includes a transformer, a power switch, a control module, and an oscillation reduction control module. A primary side of the transformer receives an input voltage, and a secondary side of the transformer is coupled to the output end. The power switch is coupled to the primary side. The control module is coupled to the power switch, controls the power switch continuously turning on and turning off, and converts the input voltage into an output voltage. When the oscillation reduction control module detects a resonance voltage through the secondary side, the oscillation reduction control module performs an oscillation reduction operation to the resonance voltage to reduce an amplitude of the resonance voltage by a damper.
