Preface
MCUs have a wide range of applications and have penetrated into almost every corner of our daily lives. Whether it is the fast charging of smart phones, the intelligent control of household appliances, or the accurate measurement of medical equipment and precision instruments, or even the automatic operation of industrial control systems and the reliable transmission of communication equipment, it is inseparable from the silent contribution of MCU.
MCU microcontrollers have become the core of promoting the intelligent control of various devices, and MCU chips integrate key components such as simplified CPU, memory, counters, and a variety of I/O interfaces to build a complete chip-level computer system, which is designed to achieve precise control of devices.
In today's PV inverters and bidirectional inverter products, MCUs also play a key role. The MCU can monitor various sensor data and adjust the power output according to the real-time load situation, improving the energy efficiency of the entire system. At the same time, the MCU also has built-in communication interfaces required by various inverters to realize the linkage with other control systems and help the whole system to achieve efficient and intelligent operation.
