A stable and sufficient power source is one of the most important indexes for industrial and economic development; since the ultra-high voltage (UHV) technology is now mature and is used for the new generation smart power network topology, not only will it be the core of smart grids in the future, it will further become the leader for promoting the development of charging piles, industrial internet, and artificial intelligence, etc. Different power equipment is needed during the transmission process of electricity from generation, transmission, transformation, distribution to terminal electricity; and during the power intellectualization process, there are also development opportunities for the sensing equipment for distribution terminals and electrical terminals. There are many different product demands for the entire power applications, and the high anti-interference design and industrial application qualities of Nuvoton microcontrollers are great for the rigorous quality and testing demands of the power industry.

Nuvoton’s industrial control Arm9 series has outstanding stability and anti-electromagnetic interference capabilities and is praised by many power equipment customers. Also, for the transformer terminal unit (TTU), feeder terminal unit (FTU) and distribution terminal unit (DTU) systems of distribution terminals, Nuvoton’s Arm9 industrial control series provide multiport that supports the RS-485/232 protocols to connect external modules, dual 100M network ports to provide remote and local Ethernet connection requirements, high-speed USB to connect wireless networking equipment, parallel RGB output and EBI interface that can both provide touch screen functions, and peripheral ports such as GPIO, ADC, PWM, SPI, and I²C, etc. to be used for the control, communication and collection requirements of power distribution equipment. The Arm9 series is equipped with industrial specifications, LQFP package, MCP DRAM, high stability, and high anti-electromagnetic interference features; these features provide an outstanding selection for customers pursuing quality, reliability, and stability under the development of the smart power industry driven by UHV.

Not only does Nuvoton provide the Arm9 industrial control series that can satisfy the requirements of power distribution equipment, with the continual pushing of intellectualization and digitization, but the number of sensing equipment is also expected to grow continually as well for the composition of a UHV smart grid. Through a shared connection of more sensing equipment, the status of the entire grid can be grasped in real-time; this is expected to be a necessary path to take for the development of the entire smart grid. Nuvoton’s ML51 low-power series can be selected for sensing equipment, including smoke detectors and liquid level sensors in substations and distribution stations; the operating power of ML51 is 80uA/MHz and can reach 1uA under sleep mode. They also have oscillators built-in, supports wide-voltage and wide-temperature operations, and have high anti-interference capabilities, etc. that makes them very suitable for different rigorous environments. The MS51 series is a great selection for power boxes, transformer, and smart locks, and other power terminals such as smart meters. The M2351 with high safety and M480 series with high performance etc. can be used; different microcontrollers can be selected for different needs.

The deployment of UHV will drive the development of various related equipment for the entire power industry from power distribution, power equipment networking platforms, sensory level small sensors, to low-power components. Nuvoton microcontrollers not only have an abundance of products with diverse combinations, but they also have features including high quality, high anti-interference, and long-term stable supply; they can create more product opportunities and commercial values for power industry customers.
