Abstract :
For the purpose of providing a natural starting point for the design of digital controllers, a small-signal sampled-data model for the constant-frequency phase-shift modulated LCC-type parallel resonant DC-DC power converter is derived. The derivations are worked out following an analytical formulation, instead of stressing numerical solutions. Simulation results and practical measurements confirm the validity of the proposed model
