Transphorm Releases New 4 KW Eval Board

News

Analogue-controlled bridgeless totem-pole design is based around 650V SuperGaN FETs

Transphorm has announced availability of its newest evaluation board, the TDTTP4000W065AN. Designed for single-phase AC-to-DC power conversion up to 4 kilowatts (kW), this board uses the bridgeless totem-pole power factor correction (PFC) topology with a traditional analogue control. This pairing provides fast and easy access to the top-notch conversion efficiency made possible by Transphorm's latest SuperGaN FETs without the need for firmware development required when using digital signal controllers (DSCs).

Maintenance power—power required to support basic functionality such as powering up and supplying chipsets—is a relatively fixed amount in any system. Therefore, as an application's power level decreases, the maintenance power becomes a larger percentage of the system's overall power loss. When compared to a DSP solution, Transphorm's analogue board requires lower maintenance power at the onset, thereby increasing overall system efficiency, according to the company.

For engineers requiring more design flexibility, Transphorm released the TDTTP4000W066C earlier this year. This DSC-based 4 kW AC-to-DC board also uses the bridgeless totem-pole PFC with the company's SuperGaN FETs. However, it integrates a dsPIC33CK DSC board from Microchip that has been preprogrammed and is backed by dedicated firmware support.

“Transphorm's analogue evaluation board provides an unprecedented opportunity to access our highly efficient GaN in the easiest way possible. Much like the preceding digital board, it gives power system engineers a choice that the high voltage device market was previously lacking,” said Philip Zuk, VP of worldwide technical marketing and North American sales, Transphorm. “Regardless of the end application's targeted value proposition, we have the diverse toolset and the most robust GaN possible to help you succeed.”

The TDTTP4000W065AN employs Transphorm's SuperGaN Gen IV TP65H035G4WS FETs in the board as the fast-switching leg with low-resistance Silicon MOSFETs in the slow-switching leg. The resulting performance is similar to that of its digitally controlled counterpart, the TDTTP4000W066C.

The TP65H035G4WS is a 650-volt device with a 35 milliohm on-resistance in a TO-247 through-hole package with an inherently high thermal dissipation ability. This feature eliminates the need to parallel devices for higher power output; a design method required by competitive surface-mount GaN solutions. And, as with all other Transphorm GaN devices, the SuperGaN FETs can be driven with a threshold voltage (Vth) of 4 volts and standard off-the-shelf gate driver operating from 0 to 12 volts.

The TDTTP4000W065AN evaluation board is currently available through Digi-Key and Mouser.
