INVERTER APPARATUS |
摘要 |
<p>An inverter apparatus is provided such that it can limit the inrush current to a smoothing capacitor of a converter at the instant of connection to AC power line. The inverter apparatus comprises a converter (3); an inverter (4); a first smoothing capacitor (12) between positive and negative buses that connect the output of the converter and the inputs of the inverter; a first resistor (14) connected in either the positive or negative bus between the first smoothing capacitors (12) and the converter (3); and first switch means (16) connected in parallel with the first resistor. A second smoothing capacitor (11) connected in series with a parallel circuit of a second resistor (13) and second switch means (15) is connected between the positive and negative buses between the converter (3) and the switch means (16).</p> |
