Abstract: The invention relates to a H-bridge inverter and a method for controlling a H-bridge converter. The H-bridge inverter (1) comprises first and second DC terminals (Tdc1, Tdc2), first and second AC terminals (Tac1, Tac2), a first switch (S1), a second switch (S2), a third switch (S3) and a fourth switch (S4). The inverter further comprises a control circuit for controlling the switching of the first, second, third and fourth switches (S11, S2, S3, S4). The control circuit is configured to control the switches (S1, S2, S3, S4) in continuous mode between the following states: a first state where the first switch (S1) is turned off, the second switch (S2) is performing PWM switching, the third switch (S3) is turned off and the fourth switch (S4) is turned on; a second state where the first switch (S1) is turned off, the second switch (S2) is performing PWM switching, the third switch (S3) is turned on and the fourth switch (S4) is turned off; a third state where the first switch (S1) is turned off, the second switch (S2) is turned on, the third switch (S3) is turned off and the fourth switch (54) is performing PWM switching; and a fourth state where the first switch (S1) is turned on, the second switch (S2) is turned off, the third switch (S3) is turned off and the fourth switch (S4) is performing PWM switching.

Abstract: An inverter system includes an input inverter including a positive and a negative DC input terminals and first and second AC output terminals; and a bidirectional inverter device, including a first bidirectional subinverter and a second bidirectional subinverter. The first and second bidirectional subinverters have DC terminals that are interconnected in parallel with a DC power storage device. The first bidirectional subinverter have first and second AC terminals. The first AC terminal is connected to the first AC output terminal of the input inverter. The second bidirectional subinverter have first and second AC terminals. The first AC terminal is connected to the second AC output terminal of the input inverter. The second AC terminal of the first bidirectional subinverter and the second AC terminal of the second bidirectional subinverter are interconnected.
