A new direct power control (DPC) strategy for open-winding brushless doubly-fed reluctance generators (BDFRGs) with variable speed constant frequency is proposed. The control winding is open-circuited and fed by dual traditional two-level three phase converters using a common DC bus, and the DPC strategy aiming at maximum power point tracking and common mode voltage elimination is designed. Compared...
The brushless doubly-fed generator (BDFG) has been considered as a promising alternative for variable speed system. The rotor structure is one of the key factors affecting the performance of BDFG and it has become the research hotspot. This paper presents a novel hybrid rotor for BDFG. The hybrid rotor structure is the combination of the reluctance structure and cage structure. In order to explain...
Electrically excited brushless synchronous motor (EEBSM) is a kind of novel motor, and the operation mechanism of EEBSM is special. In addition to the fundamental component of waveforms of stator core and rotor core flux density change which is desired, and some undesired higher harmonic components appear which leading to relatively high losses and temperature rise. Taking an 11kW and 500r/min EEBSM...
Electrically excited brushless synchronous motor is a new AC motor, which has a great difference with ordinary AC motor in electromagnetic design. Based on the electromagnetic relation of electrically excited brushless synchronous machine, in this paper the design method is studied and the electromagnetic field of electrically excited brushless synchronous machine is analyzed by finite element analysis...
This paper presents a novel type generator named brushless doubly-fed synchronous generator with hybrid rotor of reluctance and short circuit winding, and the performance of the machine is both analyzed by Finite element analysis. The validity of structure is verified by the experimental results.
The inductance method is presented for initial rotor position estimation of brushless dc motor (BLDC) in the sensorless control. This method is based on the salient effect and magnetic saturation effect of the interior permanent magnet BLDC. The method includes two processes: one estimates the rotor position of magnetic pole; the other determines the direction of the magnetization at the estimated...
