dcm-ccm

Hi guys, what happens if a buck converter that previously was designed to operate in CCM at full load (max power output) and then I connect a less load lets say 10% of the maximum load? I simulated this in LTSpice and I can see that the buck converter changes from CCM to CrCM or even DCM also I...

I built a boost converter to boost voltage from 200V dc to 400V dc. Power rating is 5kw, I added a PID to regulate the voltage. The problem is, when going from light load to heavy load, output voltage causes overshoot. After going to heavy load, further load addition has no problems. For ex...
