The training provides practical approach based on Design Oriented Analysis to develop a high performance LLC tank configuration in relation to your design targets, and selects the right components and optimizes their values, based on a power loss budgeting plan.
Design is the reverse of Analysis: one starts with specification, which is answer to the analysis, and one has to work the analysis backwards to find starting point, which is the circuit configuration and the element values. LLC converter FHA model was used to develop circuit equations that are simple yet physically insightful. Boundary condition investigation using vectors is the core of this method. Discovery of the orthogonality between inverse gain vector of the LLC and serial equivalent load vector leads to the very simple and close form equations for the LLC components. They enable seamless flow and exchange between analysis and design. Having in mind limitations of FHA model, it was necessary to bring exact solution from time domain and compare them with FHA results. It was done by using simplified LT spice simulation. Comparison resulted with generation of the ROT (Rules of thumb) for LLC design. The topic will be treated in depth on intermediate level.
