    Abstract: A power management apparatus cooperates with a controlled apparatus and is electrically connected to a power system. The power management apparatus includes an energy storing module, a switching module and a comparing module. The energy storing module is electrically connected to the controlled apparatus, and the switching module is electrically connected to the energy storing module. The comparing module is electrically connected to the switching module and receives a detection signal. The comparing module generates a periodic signal to control the switching module according to the detection signal. The energy storing module stores an electric energy during a cycle of the periodic signal and releases the electric energy during other cycle after the said cycle. Thereby, the power management apparatus is capable of effectively protecting the controlled apparatus, avoiding the waste of the power, and storing and using extra power.

    Abstract: A switching power supply system which is able to connect two or more different power sources with different voltage levels, and can provide uninterrupted power even when the primary power source is low or absent. The output voltage is much more steady than that in a conventional switching power supply and the efficiency loss is smaller as well. As a result, the backup supply time is longer than a conventional UPS system. Finally, when used in, for example, a notebook computer, there is no need to use an AC to DC adaptor when connecting to commercial AC power since the switching power supply can be directly connected to the commercial AC power for operation.

    Abstract translation: 一种开关电源系统,其能够连接具有不同电压电平的两个或更多个不同的电源,并且即使在主电源低或不存在时也可以提供不间断的电力。 输出电压比常规开关电源稳定得多,效率损失也较小。 因此,备用电源时间比传统的UPS系统要长。 最后,当用于例如笔记本电脑时,连接到商用交流电源时,不需要使用AC到DC适配器,因为开关电源可以直接连接到用于操作的商用AC电源。
