Abstract :
This paper discusses how to improve the accuracy of the gain expression obtained from the First Harmonic Approximation (FHA) for LLC resonant half bridge converter design. By reviewing the approximation, a gain compensation method is developed to improve the accuracy based on harmonic compensation. Theoretical analysis, computer simulation and bench test are presented to demonstrate the effectiveness of the proposed method.
