US-based GaN semiconductor producer Transphorm has launched a brand new 300 W DC-to-DC GaN reference design for two- and three-wheeled EV battery chargers.
The TDDCDC-TPH-IN-BI-LLC-300W-RD design makes use of TP65H150G4PS 150 mOhm SuperGaN field-effect transistors (FETs) in a TO-220 package deal to energy a high-performance, high-efficiency vitality harvesting and distribution battery charging system, in response to the corporate.
The TDDCDC-TPH-IN-BI-LLC-300W-RD board is designed for high-power-density functions such because the DC-to-DC energy stage of bidirectional DC-to-AC inverter energy provides utilized in vitality harvesting functions with solar-, battery- and grid-tied techniques in addition to AC-to-DC energy provides utilized in EV battery chargers. It options convection cooling with out compelled air, output energy of 300 W, output voltage of 48 V/6 A, 380 V/0.9 A, 97.3% peak effectivity and energy density of 36.5 W/in³.
“The primary worth proposition of GaN in high-power functions was realized by the extremely environment friendly operation of the bridgeless totem-pole energy issue correction circuit. This subsequently led to the subsequent degree of advantages throughout a wide range of topologies, together with general smaller and lower-cost energy techniques throughout the complete energy conversion spectrum, from 30 W to over 10 kW,” mentioned Primit Parikh, President and CEO of Transphorm. “We’ve now demonstrated bidirectional energy conversion that can be utilized by automobile on-board chargers for e-mobility, renewable vitality and backup energy techniques, and different energy provide functions requiring extremely built-in, interchangeable enter and output terminals.”
