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.
