具有交流电源检测电路的电源供应装置
摘要：
一种具有交流电源检测电路的电源供应装置，包含一主电源处理电路及一交流电源检测电路；该交流电源检测电路电性连接至该主电源处理电路。该交流电源检测电路包含一整流单元及一频率处理单元；该整流单元电性连接至该主电源处理电路，该频率处理单元电性连接至该主电源处理电路及该整流单元。该整流单元整流一交流电源以得到一整流电源；当该整流电源的一频率大于一默认频率时，该频率处理单元通知该主电源处理电路，使得该主电源处理电路处理该交流电源以得到一输出直流电源。
摘要（英）：

The invention relates to a power supply device having an alternating-current power supply detection circuit. The power supply device is composed of a main power supply processing circuit and an alternating-current power supply detection circuit. The alternating-current power supply detection circuit is connected to the main power supply processing circuit electrically. The alternating-current power supply detection circuit consists of a rectifier unit and a frequency processing unit; the rectifier unit is connected to the main power supply processing circuit electrically; and the frequency processing unit is connected to the main power supply processing circuit and the rectifier unit electrically. The rectifier unit rectifies an alternating-current power supply to obtain a rectification power supply. When the frequency of the rectification power supply is larger than a default frequency, the frequency processing unit notifies the main power supply processing circuit, so that the main power supply processing circuit processes the alternating-current power supply to obtain an output direct-current power supply.
