5 kW two-channel interleaved CCM PFC EVAL board
IKW40N65WR5, IDW60C65D1 and 1ED44175 in high frequency PFC application
System and functional description
2.1.1
UCC28070 - analogy controller
Infineon does not have a dedicated interleaved PFC controller, so we chose a UCC28070 from TI, which is a
popular choice in this field. Figure 5 is a simplified application diagram with UCC28070.

IDW60C65D1 – rapid1 power silicon diode
IDW60C65D1 is a 650 V/ 60 A rapid1 diode, emitter controlled power silicon diode in common cathode
configuration and in a TO-247 package, allowing design optimization for more compact dimensions, easier
assembly and consequently lower costs. Here is summary of its features:
Highest softness-factor for ultimate softness and low EMI filtering
•
1.35 V temperature-stable forward voltage (V
