In addition to automotive and consumer electronics, micro inverse is also a strong rise in chip demand.

 

 

 

On July 8, BEE Micro, Mega Innovation, Polaris Semiconductor and many other Chinese microcontroller chip makers in the field of microcontrollers at the 2024 Munich Shanghai Electronics Fair, which displayed a variety of new products once again proved that the chip field is evolving from the general-purpose arithmetic to the special-purpose arithmetic.

 

 

 

In the microinverter supply chain, the MCU (master control unit) is an extremely important part, as it is responsible for controlling the output power of the inverter, maximizing power output by adjusting the output voltage and frequency so that the microinverter matches with the grid voltage; adopting the MPPT algorithm to optimize the energy gained from each solar panel; and, in terms of intelligent functions, the MCU records operating data, controls the display and buttons and other user interfaces, and supports firmware upgrades. user interface, and supports firmware upgrade.

 

 

 

 

 

 

 

According to the statistics of ChaoDian Think Tank, the main overseas suppliers of Micro Reverse MCU are Texas Instruments (TI), NXP Semiconductors (NXP), STMicroelectronics, Microchip, Renesas, etc.; the Chinese suppliers include Mega Ease Innovations, First Oar Semiconductor, Widechip Microelectronics, BEE Microelectronics, Xiaohua Semiconductor, YiChuang Microelectronics, Coretronic, and Semiconductor. The Chinese suppliers include Joyce Innovations, First Cadence Semiconductor, Guangxin Microelectronics, BEE Microelectronics, Xiaohua Semiconductor, Yichuang Microelectronics, Xinyuan Semiconductor, Taiwei Electronics, and Joyhai Semiconductor.

 

 

 

It is worth mentioning that almost all of the above companies provide chip solutions for consumer electronics, industry, network communications, new energy, automotive electronics, Internet of Things and other fields.

 

 

 

Enphase IQ8X and other series of micro inverse MCU from the self-developed brand Enphase chip. The main control chip for most of the micro-reverse products of enterprises such as Womai, Deye, and Tianyi New Energy are provided by Texas Instruments, the world's largest analog chip maker.

 

 

 

 

 

At present, most of China's chip demand is met by imports, especially the demand for high-end chips has a large gap. Now more emerging industries are rapidly rising, the market space is attractive, attracting a large number of Chinese chip makers rookies in recent years, accelerating to fill the market gaps in technology, quality and even scale gradually catch up with overseas leading enterprises.

 

 

 

On the road of domestic substitution, China's head of the micro-reverse enterprise YuNengTechnology to demonstrate, its 250W photovoltaic grid-connected micro-reverse MCU from core science and technology.

 

 

 

In addition, there are two chip supplier powerhouse from Zhuhai. TaiWei Electronics is now launching a 600W micro-reverse MCU solution based on TAE32F5300; Polaris Semiconductor brings its MCU+ complete solutions in automotive electronics/industrial and energy/motor control, etc. to Electronica Munich Shanghai, and its latest Cortex®-M52 core G32R5 series MCUs are suitable for micro-reversal.

 

 

 

In terms of new technology, under the trend of AI big model computing demand, Mega Innovation realizes DC arc pulling detection through AI algorithm.
