1. An inverter comprising:
an AC output connected to a utility grid through a first reactor and a second reactor; an energy storage capacitor connected to a photovoltaic (PV) array terminal, wherein a first half bridge and a second half bridge respectively is connected to the positive (+) and negative (−) terminals of the energy storage capacitor, and wherein
the first half bridge comprises a first transistor and a second transistor and the second half bridge comprises a third transistor and a fourth transistor; and a first, second, third, fourth, fifth, and sixth diodes being arranged between the first half bridge and the second half bridge, the first and second diodes arranged facing the third and fourth diodes respectively each other, and the fifth diode arranged facing the sixth diode, wherein a first node of the first half bridge is connected to an anode of the first diode and a second node of the first half bridge is connected to a cathode of the second diode, a first node of the second half bridge is connected to an anode of the third diode and a second node of the second half bridge is connected to a cathode of the fourth diode, and the first, second, third and fourth diodes being formed a diode bridge, and wherein
a positive node of the diode bridge is connected to collectors of the first and third transistors and an anode of a fifth diode, the cathode of the fifth diode is connected to a positive terminal of the energy storage capacitor, and wherein a negative node of the diode bridge is connected to emitters of the second and fourth transistors and an anode of the sixth diode, and the anode of the sixth diode connected to the negative terminal of the energy storage capacitor. |
