    Abstract: A temperature detection device includes plural thermistors, a voltage source and plural temperature detection circuits. The first terminals of the thermistors are electrically connected with a common node. The voltage source is electrically connected with the common node directly. Each temperature detection circuit includes a voltage divider and a differential amplifier circuit. The voltage divider includes a first resistor and a second resistor. A first terminal of the first resistor is connected with the common node. A second terminal of the first resistor is connected with a first terminal of the second resistor and the second terminal of the corresponding thermistor. The second terminal of the second resistor is electrically connected with a ground terminal. The differential amplifier circuit includes a first input terminal connected with the first terminal of the first resistor, a second input terminal connected with the second terminal of the first resistor, and an output terminal.

    Abstract: A power supply apparatus is coupled to an AC power source, a critical load, and a general load. The power supply apparatus includes a UPS, a generator system, a power conversion system, and a controller. The power conversion system includes a first power conversion path and a second power conversion path. The first power conversion path is connected to the critical load and an output side, and the second power conversion path is connected to the general load and an input side. The first power conversion path and the second power conversion path are jointly connected to a DC bus. When the controller determines that the AC power source is abnormal, the controller controls disconnecting the AC power source, and activates the UPS to supply power to the critical load so as to enable the first power conversion path and disable the second power conversion path.
