从直流到超过开关频率一半的电力电子建模高阶广义平均法

Modeling power electronic converters at frequencies close to or above half the switching frequency has been difficult due to the time-variant and discontinuous switching actions. We develop a high-order generalized averaging method using the properties of moving Fourier coefficients to break though the limit of half the switching frequency. We also propose the high-order generalized average model ...
