Abstract
The paper describes a controller for the LCC resonant
converter that employs a Phase-Locked Loop (PLL) to
generate switch timing signals from measurements of current
in the resonant circuit. A major advantage of the control
methodology is that operation is automatically restricted to be
above the resonant frequency thereby ensuring inductive
switching. Furthermore, the 'phase-locked' nature of the
controller improves robustness by reducing the system's
sensitivity to parameter variations and permits more of the
converter's frequency characteristic to be utilised, offering the
potential for higher power densities to be achieved.
