AbsfractGtate-space modeling method for both hard- Using special simulation tools is one of the optional
and soft-switching PWM DCiDC converters is discussed ways to meet the above requirement. But these

state-space equations pact structure established many parasitic parameters that made simulations time
with Simulink, the proposed model shows high reliability consuming, and sometimes even convergence problems
and more effective performance and it is particularly would occur. Another es &om that the
suitable for steady-state analysis of soft-switching PWM solutions given by these simulation tools are not so

simulation for a hard-switching converter and another difficult to have a very clear understanding of the
example of steady-state simulation for a soft-switching behavior of the soft-swi
