| Abstract |
The paper is concerned with the stability analysis
of a feedback controlled resonant dual channel buck&boost
converter. The output voltage is controlled by using
constant frequency PWM and PI controller. The analysis is
based on the eigenvalues of the Jacobian matrix of the
Poincaré Map Function (PMF). After small perturbation
determining the deviations of the state variables from the
periodic trajectory, the Jacobian matrix is calculated
without the need to determine the PMF itself. The
introduction of the so-called auxiliary state vector greatly
facilitates the calculation. Calculation and simulation results
included helps the design of the control loop. |
