State plane analysis of a resonant DC-DC converter incorporating integrated magnetics
TLDR
In this paper, the authors developed a stateplane method of analysis of a parallel inductor transformer resonant DC-DC converter using integrated magnetics to combine in a single magnetic structure the high-frequency output transformer, the resonant inductor, and an inductor for shortcircuit protection.Abstract:
The state-plane method of analysis of a parallel inductor transformer resonant DC-DC converter is developed. A key feature is the use of integrated magnetics to combine in a single magnetic structure the high-frequency output transformer, the resonant inductor, and an inductor for short-circuit protection. Use of integrated magnetics reduces the weight, size, and cost of the converter. The design of the magnetic structure is discussed, and design equations for leakage and magnetizing inductance control are derived. The effect of the leakage inductances on the shape of the equilibrium trajectories, converter derating, and available turn-off time are discussed. >read more

Analysis and design of a fixed frequency LCL-type series resonant converter
TL;DR: In this paper, a fixed-frequency LCL-type series resonant power converter using an inductive output filter is proposed, which requires a narrow variation in pulsewidth while maintaining a lagging power factor mode of operation for very wide variation in the load.

State-plane analysis of parallel resonant converter
Ramesh Oruganti,Fred C. Lee +1 more
TL;DR: In this article, a method for analyzing the complex operation of a parallel resonant converter is developed, utilizing graphical stateplane techniques, which uncovers the presence of other complex modes besides the continuous conduction and the discontinuous conduction modes and determines their theoretical boundaries.
