Hi, i designed a buck boost converter for 12v-60A input and 36V 20A output with 200kHz switching frequency and variable duty cycle with a desired effiency of 90%. With respect to my calculations i need 1,77 uH inductor and 183 uF capacitor with 200kHz switching frequency in order to complete the circuit. I used 1,5 uH inductor (in the picture there are 2 inductors parallel but i tried the circuit with 1 inductor) and 200 uF capacitor. When i start the power supply with 12V 1A limits, power supply gives 1A constantly and the mosfet acts like short circuit because of the inductor and heats up too much, and i only get 19V output. I don't know where i did wrong and any help is much appreciated.
