| Abstract |
The paper deals with a dual channel resonant DCDC
Buck converter analyzing the high switching frequency
region of its operation. In the converter the energy is
transmitted through two channels from the input to the output
using a switched capacitor. Due to the two channels its
application is recommended in the medium or higher power
ranges. An advantage of the converter is that in discontinuous
current conduction mode (DCM) it can work in soft-switched
mode too. A drawback of DCM operation is the higher output
voltage ripple and the unfavourable utilization of the power
transmission capabilities of its components compared to the
continuous current conduction (CCM) operation. The main
objective and the original contribution of the current paper are
to present the conditions of the operation above the resonant
frequency of its inherent ringing circuit, and to represent its
beneficial effects. The considerations are verified by simulation
results. |
