Minimization effect of reverse recovery using IGBT

This work looks at on how reverse recovery affects the DC-DC converter system with respect to switching frequency and gate resistance of the inductive chopper circuit. Single Cuk converter with IGBT power switch (IRGBC40F) and power diode (UT268) is used as the test circuit. It is found that by increasing the switching frequency, higher reverse recovery power dissipation is observed having lower reverse recovery peak current. On the other hand, these two parameters are inversely proportional to the increase in gate resistance. Efficiency and output voltages ripples are then concluded.
