In booth 4D18 at PCIM (Power Conversion Intelligent Motion) Asia 2015 in Shanghai (24–26 June), GaN Systems Inc in Ottawa, Ontario, Canada – a fabless developer of gallium nitride (GaN)-based power switching semiconductors for power conversion and control applications – is showcasing a new addition to its range of GaN high-power transistors for the first time in China. The firm is also demonstrating production models of real customer applications using its devices. PCIM Asia is GaN Systems' first major exhibition in China, which it expects to become an important market as GaN power transistors increasingly replace silicon semiconductors in power electronics.
The new 60A GaN high-power enhancement-mode device (the GS66516T) expands GaN Systems' range of power switching semiconductors, which it claims is already the broadest product offering on the market (with current ratings ranging from 8A to 250A). Based on the firm's Island Technology die design and packaged in low-inductance and thermally efficient GaNPX packaging, the GS66516T also features new proprietary top-side cooling technology (announced in March),, enabling it to be cooled using familiar and conventional heat-sink or fan cooling techniques.
The firm says that, as gallium nitride technology moves into mainstream production in markets ranging from consumer to industrial and clean tech, early adopters have already released products onto the market that take advantage of GaN Systems' technology, which harnesses the superior fast switching performance of GaN and reduces power losses by up to 90%, resulting in smaller and far more efficient power electronics.
Also at PCIM Asia, GaN Systems is demonstrating a 650V 30A 3-phase inverter power module from Korea-based LS Industrial Systems, which focuses on delivering safe clean energy. Also being shown is a new 3kW, 800/380V DC/DC bi-directional converter developed by the NextHome consortium in the USA, a group of consumer electronics manufacturers who are developing new energy-efficient power systems for use in the home.
