  • Advanced circuit arrangement of transformerless 1 phase PV inverter
    Patent number: 9093922
    Abstract: Disclosed is an inverter with outputs being connected through two reactors to a utility network, while an energy storage capacitor (C) is connected to the PV array (P) such that the C + and ? terminals are connected to two half bridges creating an H bridge so that the AC node of one half bridge is connected to the anode of a diode (D1) and the cathode of a diode (D2). An AC node of the other half bridge is connected to an anode of a diode (D3) and a cathode of a diode (D4), while the diodes form a diode bridge having a positive node connected to a transistor's (V5) collector and an anode of a diode (D5), the cathode of the diode (D5) being connected to C's positive terminal.
