INVERTER CONTROL METHOD |
| 摘要 |
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. |

1. A method of controlling an inverter, the inverter including a single-phase inverter arrangement comprising a complementary pair of power switches,
the method including 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. |
