Efficiency Analysis of PSM Boost Converter by Energy Balance Model

摘要：

Pulse Skip Modulation (PSM) is one kind of modulation modes in power converters, which is different from PWM, PFM. Based on the theory of energy conservation, the energy balance (EB) model for PSM Boost converter in DCM (Discontinuous Conduction Mode) is proposed in this paper. Based on the EB model in which all system dissipation is considered, the efficiency of PSM Boost converter operated in DCM is investigated using MATLAB simulation. The comparison with PWM Boost converter under the same circuit parameters with MATLAB and HSPICE simulation proves that PSM converter has higher efficiency at light load.
