Buck converter for SSL applications
During the time
1
t
total
(Mode 1), switch S1 is switched on and a current starts to flow
through inductor L. At the moment switch S1 is switched off, the secondary switch S2 is
closed and a current flows towards the output. During the conduction time of switch S2,
the energy in the inductor is reduced. The time interval
3 is entered when the current
through switch S2 has decreased to zero. This mode of operation is referred to as the
Discontinuous Conduction Mode (DCM). The border between DCM and Continuous
Conduction Mode (CCM) is reached when the time
3
t
total
has become zero. This is
referred to as the Boundary Conduction Mode (BCM). The CCM mode is present when
the inductor current does not reach zero throughout the cycle.
