    摘要： A method for controlling the power system is presented. The power system is composed of at least one inverter for supplying AC power to a load through a bus, a phase lock system to synchronize all output voltages of the inverters and a current sharing circuit to properly distribute the load current among all inverters. Each inverter is controlled by an unbalanced power to limit the increase of its cross current. Moreover, the information related to DC bus voltage is further applied to control the inverters, whereby the cross current is mitigated and entire power system is operated steadily.

    摘要： An optical receiver. The optical receiver includes a photodiode, a differential transimpedance amplifier, a transistor, and a current source. When the photodiode receives an optical signal, a current signal transmitted from a cathode of the photodiode to an anode thereof is generated. Two input terminals of the differential transimpedance amplifier couple the current signal, and the differential transimpedance amplifier converts the current signal to a voltage signal. In addition, voltage variation of the cathode is coupled to the anode through a voltage follower composed by the transistor and the current source. As a result, voltage of the cathode and that of the anode vary in phase, effectively decreasing a value of the photodiode parasitic capacitance and improving operating bandwidth.

    摘要： An optical receiving device. The optical receiving device has a photodiode, transimpedance amplifier, and a feedback component. The photodiode has a first terminal coupled to a voltage source and a second terminal. When detecting an optical signal, the photodiode generates a current signal output from the second terminal. The transimpedance amplifier converts the current signal to a voltage signal and outputs the voltage. The feedback component is coupled between the first terminal and a input terminal of the transimpedance amplifier. The feedback component feeds a first voltage-changing signal, occurring in the input terminal of the transimdepance amplifier with the current signal, to the first terminal.
