摘要

世界上有限的能源资源促进了太阳能等可再生能源的利用。这可以利用光伏板，它需要最大功率点跟踪(MPPT)技术来最大限度地利用面板输出功率。在跟踪算法中，该方法采用了Perturb和Observe (P&O) MPPT。P&O控制器控制zeta变换器的占空比，最终控制无刷直流(BLDC)电机。电机的速度可以通过调整变频器直流环节的电压来控制。为此，提出了一种PV供电Zeta变换器馈入无刷直流驱动模型。在PSIM中进行了仿真，验证了模型的有效性。

PV powered zeta converter fed BLDC drive

The limited energy resources in the world promotes the increased utilization of renewable sources like solar energy. This could be harnessed using photovoltaic panels, which require Maximum power point tracking (MPPT) techniques to have the maximum usage of the panel output power. Among the algorithms for tracking the proposed method uses Perturb and Observe (P&O) MPPT. The P&O controller controls the duty cycle of the zeta converter, which finally controls the brushless DC (BLDC) motor. Speed of the motor can be controlled by adjusting the voltage at the dc link of the inverter that feeds the motor. Thus a PV powered Zeta converter fed BLDC drive model is proposed. The effectiveness of the model is verified using simulation done in PSIM.
