PM generator with series compensated diode rectifier

Övrigt konferensbidrag, 2000

This paper presents an investigation of a series compensated diode rectifier for permanent magnet generators. Series compensation has the advantage that the reactive power produced by the compensation follows the variations in the generator's reactive power consumption, as the generator currents change. The investigation show good performance at speeds close to rated speed, and show problems of generating high power at low speed. The investigation also shows that series compensation works well in the whole operating range of a wind turbine generator system. However, the behaviour under abnormal operating conditions remains to be studied.
