- Abstract
The classical switching‐table‐based direct power control usually employs one active voltage vector during the whole sample period, which will bring distinct current harmonics and large power ripple. This paper proposes an improved deadbeat direct power control for a dual three‐phase permanent magnet synchronous generator. The deadbeat control of both active power and reactive power is employed to calculate the duty cycle of the active vector. By this way, the active and reactive power can follow the references as much as possible during each sample period. Then a weight coefficient is introduced and its effects on the steady‐state performances of active and reactive power are analysed. With this proposed method, the current harmonics and power ripple are suppressed considerably. Meanwhile, the simple structure and fast dynamic response are preserved. The experimental results validate the effectiveness of the proposed strategy.
