研究目的
To regulate the speed of SRM drive to pump the water through the DC link voltage of a mid-point converter.
研究成果
The paper concludes that the solar PV array fed water pump system using an SRM drive is more efficient and reliable than systems based on DC or induction motors. The use of a buck-boost dc-dc converter in continuous conduction mode (CCM) reduces stress on power drives, and the mid-point converter minimizes switching losses. The incremental conductance (InC) MPPT algorithm effectively tracks the maximum power point, reducing oscillations and power loss.
研究不足
The paper does not explicitly mention limitations, but potential areas for optimization could include further reduction of switching losses and enhancement of the MPPT algorithm's efficiency under rapidly changing environmental conditions.
