Abstract:
This paper presents development of a
performance analysis of neuro fuzzy controllers to
overcome the appearance of nonlinearities and
uncertainties in the LLC resonant converter. This paper
addresses a LLC resonant converter circuits are built for
low output voltages (24 V) and such circuits can be useful
for Telecom and server application. For obtaining the DC
voltage transfer function Fundamental Harmonic
Approximation (FHA) method has been adopted. Important
issues of this converter are physical size, high conversion
ratio, efficiency, and startup. The proposed topology has
energy conversion efficiency of 92%, when operated at fully
loaded condition. A neuro fuzzy controller based LLC
isolated DC–DC converters are also proposed to regulate
over wide range of loads. Switching losses are minimized by
zero voltage switching by the use of resonant inductor and
capacitor. This converter has advantages like low switching
loss, less EMI, and less switching stresses.
