    摘要: A hybrid DC-to-AC conversion system includes a first DC input voltage, a second DC input voltage, a power conversion apparatus, and a comparison unit. The power conversion apparatus is connected in parallel to the first DC input voltage and the second DC input voltage to convert the first DC input voltage or the second DC input voltage into an AC output voltage. The comparison unit receives the AC output voltage and an external reference voltage. The comparison unit outputs a control signal to make the first DC input voltage supply a load when an absolute value of the AC output voltage is less than or equal to the external reference voltage, whereas the comparison unit outputs the control signal to make the second DC input voltage supply the load when the absolute value of the AC output voltage is greater than the external reference voltage.

    摘要: A photovoltaic powered system with an adaptive power control and a method of operating the same. A photovoltaic panel is provided to generate electric power to supply a load. The photovoltaic powered system includes a charging control unit, a rechargeable battery unit, a first switch unit, a second switch unit, a power condition unit, and a switch control unit. The switch control unit turns on the first switch unit and turns off the second switch unit when the photovoltaic panel can generate the electric power, thus supplying the load and charging the rechargeable battery unit, respectively. The switch control unit turns off the first switch unit and turns on the second switch unit when the photovoltaic panel cannot generate the electric power, thus providing energy stored in the rechargeable battery unit to supply the load.

    摘要: A DC to AC converter includes a first switch, a second switch, a first half bridge inverter, and a second half bridge inverter. The first switch includes a first terminal and a second terminal. The second switch includes a first terminal and a second terminal. A portion between the first terminal of the first switch and the first terminal of the second switch is operable to receive a direct current power source. The first half bridge inverter includes a first terminal, a second terminal, and an output terminal. The second half bridge inverter includes a first terminal, a second terminal, and an output terminal. A portion between the output terminal of the first half bridge inverter and the output terminal of the second half bridge inverter is operable to output an alternative current.
