  "textContent": "The compensator (10) has a control unit (22) comprising a computation unit to generate a target control current from a current to be compensated. A combining unit combines the target current and an alternating output current from a voltage inverter (20) to supply a differential current. A correction unit of the control unit adds a balancing current to the target current for correcting the target current to reduce difference between values of two voltages (V-dc1, V-dc2), where the target current is increased for an even harmonic of a frequency of an alternating-current electrical network (12). The balancing current is a periodic frequency signal or a sinusoidal frequency signal equal to a non-zero even multiple of the network frequency. The values of the voltages are obtained at terminals of capacitors (C1, C2) of the inverter, respectively. An independent claim is also included for a method for balancing half-bus voltages in a reactive energy compensator.",
