Focusing on semiconductor devices in micro inverters
The power of micro inverters is generally between 250W and 1500W, and the semiconductor devices used include MOS transistors (60V-150V, 600V-950V), SiC MOS transistors (650V, 1200V), GaN (600V), gate driver ICs, SiC diodes (650V/1200V), communication chips (Wi Fi, Bluetooth, PLC), auxiliary power modules, storage chips, current detection chips, MCUs, etc.
The positioning of semiconductor devices in the micro inverter market is the core technology component, playing a key role in energy conversion and control. For example, the core function of micro inverters is to convert the DC power generated by photovoltaic modules into AC power suitable for integration into the grid. Power devices such as MOSFETs, IGBTs, etc. are used as switching elements inside the inverter, responsible for high-frequency switching operations during the DC-AC conversion process, directly affecting the conversion efficiency, power density, and reliability of the inverter. Its functions such as overvoltage protection, overcurrent protection, and short-circuit protection ensure that the system can respond quickly in abnormal situations and avoid equipment damage.

In the photovoltaic industry chain, third-generation semiconductors such as SiC have superior characteristics compared to Si in terms of bandgap energy, breakdown field strength, thermal conductivity, and other parameters. These characteristics allow SiC systems to operate at higher frequencies without losing output power, thereby reducing the size of passive components (especially inductors). Therefore, using SiC in micro inverters can improve inverter efficiency, reduce energy loss, and have more significant performance advantages in high temperature environments, which helps to improve the overall power generation efficiency of the photovoltaic system.
In addition, due to the high efficiency and good heat dissipation performance of SiC, inverter design can use smaller heat dissipation devices and more compact packaging, thereby achieving miniaturization and lightweighting of inverters, which is particularly important for micro inverters. Because they usually need to be installed on rooftops or other places with limited space, and their light weight is beneficial for simplifying installation and reducing installation costs. SiC also has a wide range of applications in commercial string inverters, energy storage and other microgrid and off grid system environments.
As a typical representative of third-generation semiconductor materials, how does GaN perform in micro inverters? Cold Yongsheng, a research and development engineer at Hemai Corporation, said, "GaN has some problems that people are not willing to use because it is easy to damage and unstable. Its driver requires special design, which is significantly different from previous devices. In comparison, SiC performs more stably in terms of performance
According to Fu Youwen, the Marketing Director of Shilan Microelectronics' Finished Product Line, Shilan Microelectronics has leveraged its IDM integration advantage and based on Shilan's compound semiconductor production line, launched 1200V SiC chip performance indicators that have reached the international leading level. At the same time, it has also developed high-performance SiC MOSFET chips in voltage ranges such as 650V, 1700V, and 2000V, as well as various packaging forms including TO-247B-4L, TO-263-7L, TOLL, B10, B15, D4, etc., which are suitable for photovoltaic energy storage inverter applications.
