Half Bridge Measurement

Following is the result of our experiments on HB_EVB_PWR_ISL_V2
half bridge evaluation board with two V22N65A All switches and active air
cooling using 1.5W fan.
Testing parameters:
– Continues Current Mode
– Switching frequency 200KHz
– Duty Cycle 60%
– Dead Time 100ns

Vin = 399.935VdcIin = 6.22A
Vout = 229.67Vdc Iout = 10.694A
Pin = 2487.6WPout = 2456.1W
Rise time = 8.8ns Fall time = 17.8ns

 

Efficiency = 98.7%

Temp. of high side switch after 15 minutes of work = 67°C

Temp. of low side switch after 15 minutes of work = 32°C
