Abstract :
A nonlinear control law for a class of resonant converters is proposed. The departure point is the mathematical models found in a previous work, to which a stabilizing feedback law is applied. The theory is confirmed by simulations. The principle of the control law consists in finding a state feedback which makes a given submanifold attractive. The proposed control law is defined everywhere (i.e. it has a global character), is stable, and does not depend on the load variations, so that it constitutes a robust manner of control
