Constant Current Frequency Tracking in LCC Converters
An LCC resonant converter when operating at a certain frequency performs as a current source that is independent of the load resistance. This frequency is dependent only on the values of the capacitors and inductor of the tank. Unfortunately, the values for these components are usually specified within a certain precision by manufacturers. Furthermore, factors such as temperature affects these values. This paper proposes a control scheme for setting the frequency of an LCC resonant converter at the unloaded natural resonant frequency. This allows the system to lock on to the load independent frequency despite the issue of component value precision. Analysis of the system, which aims to be used as an LED driver in smart farm applications, is discussed. A 64w LCC converter is designed and simulated to test the control scheme.
