According to James Consulting, at the Asia-Pacific Economic Cooperation summit in 2018, Menlo Micro presented a new 200V/10A digital micro-switch smart power relay technology.
At the Asia-Pacific Economic Cooperation summit on March 6, 2018, Menlo Micro issued Buchi's latest 200V/10A digital micro-switch (DMS) intelligent power relay technology. This technology is a key milestone for Menlo Micro's digital MEMS switch platform.
The new DMS intelligent power relay technology opens the door to a broad vertical market segment. To date, many companies have had to endure the limitations of solid-state relays, including high leakage currents, lack of air gaps, and complex heat dissipation, or they have to choose slow, bulky, and expensive electromechanical relay solutions.
“Our DMS technology enables ultra-small, ultra-light power relays that combine the best features of solid-state and mechanical devices,†said Chris Giovanniello, vice president of product development at Menlo Micro. “The market is constantly demanding reductions in size, weight, power and cost. It is now able to meet this demand and create a new control product for the industrial IoT market."
To demonstrate the scalability of the technology, Menlo Micro combines more than 200 MEMS high-voltage switches on the Smart Power Relay Evaluation Board with integrated protection and control systems. This credit card-sized evaluation board can carry 10A DC current without the need for heat dissipation. This MEMS switchgear's ability to handle currents has reached unprecedented levels thanks to Menlo Micro's unique materials, design and wafer level processing technology.
High-power, high-reliability RF switches from Menlo Micro are already being used in medical instruments, test and measurement equipment, and reconfigurable software radios. Typically, these switches are three-terminal devices that operate from 25W to 50W. For intelligent power relays, Menlo Micro has created a fully isolated four-terminal architecture with advanced features such as overcurrent protection. The advantages of this DMS power relay architecture include the following:
- Reduced volume and weight by 80%. Each wire between the metal and the metal is smaller than the width of the human hair, even if combined into a large array, it produces only a very low on-state loss (< 10mohm) in a small package, eliminating the need for large and heavy heat dissipation. Device. This will bring a new form of design to power electronics designers.
- Switching speed is up to 1000 times faster than conventional electromechanical relays.
- Intelligent features. DMS power relays not only retain the electrical isolation characteristics of traditional mechanical relays, but also integrate into traditional semiconductor packages such as system-in-package or multi-chip modules, which enables system designers to provide other more useful intelligent features. And more efficient.
- Semiconductor cost structure. Menlo Micro's DMS technology uses wafer-level manufacturing process technology. This allows DMS products to benefit from the scale and cost structure of semiconductor products.
- Menlo Micro's DMS Smart Power Relays are ideal for home and building automation, industrial automation control, robotics, electric vehicles, battery management and electronics.
At this week's Asia-Pacific Economic Cooperation Industrial Applications Conference, IEEE Fellows Dr. Liu Yanfei and Menlo Micro published a paper entitled "High-Voltage MEMS Relay Design for Zero-Voltage Power and Signal Conversion Breaking", which Menlo Micro introduced in detail. The structure of this new smart power relay.
Menlo Micro's DMS power relay technology is currently undergoing usability assessments among its key industrial partners.
