Transphorm, Microchip team for 3 kW GaN inverter
Transphorm has launched its third high-power GaN design tool using a digital signal controller from Microchip Technology for 3kW designs.
The TDINV3000W050B-KIT is a 3.0 kW DC-AC non-isolated full-bridge inverter evaluation board that pairs Transphorm’s TP65H050G4WS SuperGaN FET with Microchip’s dsPIC33CK digital signal controller (DSC) board. The TP65H050G4WS is a 650 V 50 mΩ SuperGaN FET in a TO-247 package
The DSP board includes pre-programmed firmware that can be easily customized per end application requirements in broad Industrial and renewables power systems and the design has an efficiency of 99%
As with the previous two SuperGaN/Microchip DSC evaluation boards (the 4 kW TDTTP4000W066C-KIT) and the 2.5 kW TDTTP2500B066B-KIT), the single-phase 3.0 kW inverter board is backed by access to Microchip’s worldwide technical support team for firmware development assistance.
“Our dsPIC digital signal controllers and firmware customization expertise complements Transphorm’s GaN technology and helps accelerate development while simplifying the design” said Joe Thomsen, Vice President, MCU16 Business Unit at Microchip. “Working together with Transphorm, we are proud to enable flexible and highly efficient power conversion to address a wide range of sustainability applications.”
“High voltage power systems such as EV Chargers, UPS, and Solar Inverters are quickly becoming rapid growth markets for GaN. Transphorm’s GaN platform was developed with such applications in mind,” said Philip Zuk, SVP of Business Development at Transphorm.
“Working with Microchip on the firmware side enables us to support important, sustainable customer power system projects in a highly efficient manner. It removes potential limitations that may be experienced with firmware programming, simplifying development and speeding time to market. This collaboration allows renewables and other industries to easily leverage all our GaN has to offer.”
The board is designed around Microchip’s dsPIC33CK digital power plug in module (PIM) to control the PFC powertrain, with the AEC-Q100-qualified 100MHz dsPIC33CK256MP506 digital signal controller based around a dsPIC DSC core with integrated DSP and enhanced on-chip peripherals. It has 8 independent PWMs pairs with 250 ps resolution. Firmware updates for the dsPIC33CK PIM will be available for download from Microchip’s website.
The evaluation board is designed for use when developing vehicle-to-grid (V2G) charging systems, solar or photovoltaic (PV) inverters, uninterruptible power supplies (UPSes), and other high voltage power applications. It is available through Digi-Key and Mouser.
