METHOD OF OPERATING AN INVERTER BY TURNING OFF THE SWITCHING AROUND A ZERO TRANSITION OF THE ALTERNATING OUTPUT CURRENT |
摘要 |
A method of operating an inverter for converting direct voltage into alternating voltage. The inverter has direct-voltage terminals and alternating-voltage terminals and a plurality of power switching elements that are clocked at high-frequency connected between the d.c. and a.c. terminals. The high-frequency clocking of the power switching elements of the inverter is switched off around a zero transition of the alternating current or the alternating voltage for a period which depends on the direct voltage present at the direct-voltage terminals of the inverter and/or the output power of the inverter. No current is generated during time intervals with a poor efficiency. |
