Abstract :
The quasi-resonant operation mode of the Cuk converter is
characterized by discontinuities in the current of output diode and
in the voltage of the intermediate capacitor. Therefore all the
commutations are soft, allowing the increase of the switching
frequency maintaining an acceptable efficiency and increasing the
power density. The inductors can be selected so as to have
continuous input or output current, resulting in different converter
behavior. This paper presents a methodology to calculate the values
of the inductors and capacitor to ensure the correct operation. The
converter is PWM controlled.Simulated and experimental results are
reported.(Author abstract)
