GaN Systems demonstrating wireless power transfer and commercial power systems at APEC
In booth #1501 at the Applied Power Electronics Conference and Exposition (APEC 2017) in Tampa, Florida (27-29 March), GaN Systems Inc of Ottawa, Ontario, Canada – a fabless developer of gallium nitride (GaN)-based power switching semiconductors for power conversion and control applications – is giving live demonstrations of commercial systems that use GaN transistors in wireless power transfer and power module applications. The event also showcases customer-built, commercial systems that use GaN transistors to power a diverse range of applications, including DC/DC converters, energy storage systems, and electric vehicle (EV) traction inverters.
Among the new systems enabled by GaN transistors that will be demonstrated by GaN Systems are:
- a 150W transmitter wirelessly powering an airborne drone in real-time, operating at 13.56MHz;
- a 5-10kW half-bridge power block (eight paralleled GaN transistors and a matching driver card, forming a complete building block for high-power systems);
- a detailed head-to-head comparison that shows how GaN outperforms silicon carbide (SiC);
- a best-in-class, AirFuel-compliant wireless transmitting platform capable of charging multiple phones, pads and laptops, scalable and adaptable for use in toolboxes, factory robots etc; and
- an ultra-small, highly integrated 1MHz LED driver, constructed using a GaN-enabled architecture.
In addition, also on display are newly commercialized GaN transistor-powered systems, including:
- a 10kW, 3-phase solar inverter over 100 times smaller than silicon-based designs;
- a 99%-efficient, 3kW power factor correction (PFC) reference design;
- demonstration boards from leading semiconductor partners (Analog Devices, Linear Technology and Peregrine Semiconductor);
- A 48V DC-DC demonstrator that shows what is claimed to be outstanding efficiency, and is suitable for automotive and data-center applications;
- a 3-phase motor controller that operates at optimal efficiency;
- a universal motherboard and daughterboard platform for easily evaluating GaN transistor performance in any half-bridge-based topology; and
- GaN-based motor drives for various applications ranging from 1.5kW to 30kW.
