Title :
The control of quasi-resonant converters
Author_Institution :
Brighton Univ., UK
Abstract :
The small-signal transfer functions of the buck quasiresonant power converter have been derived. The derived small-signal transfer functions have been used to design the control circuit for this converter. Based on the small signal analysis, the control circuit has been designed (using multi-loop control), simulated, built and tested with the power converter. By using this control scheme, the converter provides very good transient response and a stable system. The same technique can be used to design the control circuit for other quasiresonant converters
