  • Publication number: 20140064940
    Abstract: A casing of a turbocharger has a main body and a heat dissipating layer disposed on an outer surface of the main body. When heat inside the main body is conducted to the outer surface of the main body, the heat dissipating layer dissipates the heat quickly. Since the heat does not accumulate in the main body, temperature of the main body is low and the casing does not oxidize under high temperature. Therefore, the casing of the turbocharger has low manufacturing cost and is economical.

  • Patent number: 8570018
    Abstract: A synchronous buck regulator includes a voltage regulator, a sample unit, a switch element, a comparison unit, a time delay unit, and a control unit. The sample unit is connected to the external power source for sampling a voltage drop in the external power source. The comparison unit is connected to the sample unit for outputting a result-high signal when the current passing through the sample unit is greater than a predetermined current rating. The time delay unit is connected to the comparison unit for outputting a first result-low signal. The control unit is connected to the time delay unit and outputs a first a low level signal to the switch element according to the result-low signal. The switch element connects the sample unit and the voltage regulator and can isolate the voltage regulator from the external power source when the low level signal is received.

  • Publication number: 20130169052
    Abstract: An power supply includes an output terminal, a switch module, a battery module including batteries, and a controller storing a threshold voltage and detecting an output voltage of the battery module. The battery module is connected to the output terminal through the switch module. One battery outputs the supply voltage until an output voltage of the battery is lower than the threshold, and then another battery outputs the supply voltage under control of the controller. The controller repeats such control until the output voltage of each battery is lower than the threshold. Then the controller instructs two or more batteries to be connected in series through the switch module, and in combination output the supply voltage to the load. When the output voltage of all the batteries connected in series is lower than the threshold, the controller controls the switch module to be disconnected from the output terminal.
