This paper presents the use of a resonant circuit for fast voltage recovery of power supplies under large-signal load transients. Previous works have shown that an augmentation circuit (or auxiliary circuit) for voltage recovery may be used to improve the dynamic response, while the main converter is operating for current recovery with load current feedforward control. A compact, low cost and magnetic-coreless topology with a simple control algorithm to achieve an augmentation circuit is presented. In the prototype, the inductors are realized using printed copper wires. The control algorithm is realized by a low cost and low density logic device. Simulation and experimental results validate the feasibility and effectiveness of the circuit.
