Continuous and discontinuous current mode
WebOct 13, 2013 · The average value of the output of a buck converter in discontinuous mode is still the same as continuous mode. However, the ripple voltage increases. This happens on light loads when the switcher cannot produce pulses of low enough duty cycle and it transfers a little too much energy per switching cycle for the light load. WebMay 3, 2004 · Continious Current Mode (CCM) means that current through inductor flows continuously throughout the switching period (always >0). Discontinuous Current Mode …
