Description: 许多有用的地理位置，太阳能为动力的水泵是特别有利的偏远地区，那里可能没有常规电源提供地下水。令人印象深刻的CY8C27443微控制器为基础的太阳能水泵控制器采用了混合信号阵列，可控制的三阶段电机驱动经营潜水水泵直接从太阳能电池板。
强大的PSoC微控制器提供了三相PWM生成，信号调理，过电流和短路保护，温度监测，并不断的电压频率控制。此外，微控制器CY8C27443最大的电力来自太阳能电池阵列。这样做的结果是强大的，低成本，高效率的控制器。-Solar Pump Controller
Useful in many geographic locations, solar-powered pumps are particularly advantageous in remote areas, where there may not be conventional power to provide ground water. The impressive CY8C27443 microcontroller-based Solar Pump Controller features a mixed-signal array that controls a three-phase motor drive to operate a submersible water pump directly from solar panels. The powerful PSoC microcontroller provides three-phase PWM generation, signal conditioning, over-current and fault protection, temperature monitoring, and constant voltage-to-frequency control. Additionally, the CY8C27443 MCU maximizes the power from the solar array. The result is a robust, low-cost, highly efficient controller.
