V. CONCLUSION
Due to the highly development of semiconductor,
the development trend to obtain compact size, high
efficiency, light weigh for a flyback converter can be
easily reached. It then becomes one of the most
important components in the electrical or electronic
device. With respect to the design complexity,
particularly, when it is installed nearby or on the system
board and traditional try-and-error method of hardware
implementation is applied, the development schedule
duration and human resources will be more critically
concerned. Based on this, in order to solve this crucial
problem, a solution of circuit design by building the
component models and employing the circuit simulation
prior to a practical power converter being realized, is
presented in this paper. Further, according to theoretical
analysis of the flyback converter, the modeling for each
component will be subsequently built by using the
IsSPICE circuit simulation software and simulated in
respect to the open-loop control and closed-loop control.
The simulation results show the verification and integrity
of designed system configuration through theoretical
analysis and derivation. Based on the complete
simulation results, a practical flyback converter scheme
is realized and implemented. The measuring results from
the practical circuit verify with that of the simulation.
Although some of the values between realization and
simulation exist minor difference, they are still within
the error tolerance. Therefore, the models of the flyback
converter derived and built by using the circuit
simulation software, have been proved to be successfully
realized in this paper. Consequently, it then can avoid
the more human resources being involved while a
practical circuit is developed and realized. Moreover, it
can shorten the development schedule duration and raise
the productivity, further, increase the ability of market
competition for a manufacture.
