概述
描述
农业是许多人生活的重要组成部分，但不断上涨的水和能源成本使依赖电网电力或柴油发电机的传统灌溉系统越来越昂贵。 因此，人们对太阳能替代品和节能节水智能功能的需求日益增长。
瑞萨电子提供绿色能源系统来满足这一需求，提供适用于各个地区的高效且可持续的灌溉系统。 通过利用太阳能和利用最大功率点跟踪（MPPT）算法，该系统最大限度地提高了能源效率，并减少了农业高峰期对电网的依赖。 用户友好的界面允许对灌溉计划和电机速度进行隔离、可编程的控制，为高效和可持续的农业灌溉提供灵活性和精度。
系统优势：
- 与交流和 PMSM 电机兼容，使用先进的变频驱动（VFD）和磁场定向控制（FOC）技术，可在各种农业应用中实现最佳性能和成本效益。
- 利用带有浮点单元（FPU）的 MCU 实现高效的单逆变器控制。
- NB-IoT 和低功耗蓝牙®（LE）模块可实现有效的动态数据采集和诊断。
- 太阳能泵控制器零排放温室气体，减少碳足迹。
- 实施单分流、支腿分流和面板分流，以增强保护。
