This paper presents the implementation and design of a power converter for an autonomous wind self-excited induction generator (SEIG) feeding an isolated load through the employment of a DSP-based rectifier-inverter circuit. The output voltage and frequency of the studied wind SEIG is inherently variable due to random fluctuation of wind-speed variation. A three-phase constant-voltage constant-frequency...
This paper presents a voltage controlled scheme for brushless DC (BLDC) motor drives. The scheme combines both the low speed PWM control and the high speed phase advance commutation to obtain an extended speed range drive feature. In addition, the proposed scheme does not have a current control loop. Hence, no current sensor is needed in the drive. To satisfy the required over load protection demand,...
