A method of controlling an inverter, in which the inverter includes a single-phase inverter arrangement comprising a complementary pair of power switches, comprises the steps of:
controlling the complementary pair of power switches with a modulating signal to output an AC signal;
judging which of the power switches in the complementary pair of power switches is at a higher temperature;
determining the magnitude and sign of a DC offset signal to apply to the modulating signal to reduce the total current in the power switch judged to be at the higher temperature; and
applying the DC offset signal to the modulating signal. |
