Typical Eciency for a Boost 200V:400V Converter
g The TDHBG1200DC100 board can deliver 1200W with forced air cooling when
congured as
• 200V to 400V boost, 100kHz, or
• 400V to 200V buck, 100kHz
g Dierent input/output voltage and power can be chosen, however
• Input/output voltage should not exceed 400V
• In each GaN FET, the rms current should not exceed 7A
• Users should monitor the device temperature to make sure they are not being
overheated by excessive power during the test
g Driver deadtime is preset to 120ns for typical operation and can be adjusted
for dierent operating conditions; please refer to the TDHBG1200DC100 User Guide
