In order to transfer maximum power to a DC
load, employment of a suitable compact converter that not only
could operate at high frequencies but also exhibit minimum
switching losses is necessary. Resonant convertors are
proposed for this purpose. To maintain system operation at
maximum efficiency at variable loads, a simple and reliable
control method is required which continuously tracks the
circuit variable resonance frequency. In this paper a Digital
Phase-Locked Loop (DPLL) circuit is designed and deployed in
order to adjust a12 V DC output and 300 watts, LLC Resonant
Converter operation frequency. The complete system
performance is evaluated based on simulation. Simulation
result shows that by using DPLL control method, the phase
difference between resonance tank current signal and class D
inverter output voltage signal becomes constant and switching
frequency always follows resonance frequency which will
guarantee minimum power loss.
