Abstract OGY method(1990) is applied to control the chaos exhibited by current-mode controlled boost dc-dc converter, as its chaotic regime has been established in this paper. This is achieved by using discrete-time model and making simplification of the control loop design. Both simulation and experiment are done. Stability of the circuit is obtained, which proves this control method is valid in controlling switching circuit.
