225 - Nguồn Xung Buck Dòng Liên Tục và Không Liên Tục

In this clip, I explained about the circuit operation of the Buck converter in Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM). The feedback control in this circuit is a voltage feedback. The control (VEA) to output transfer function (Vo) is changed from a two poles equation (CCM mode) to a single pole equation (DCM mode). In addition, the duty cycle is also changed between the two modes (see slice #6 and #7).
