Full Order Models and Simulation of Boost Converters Operating in DCM

State-space average-value modeling of pulse-width modulation (PWM) converters in continuous and discontinuous modes has received significant attention in the literature, and various models have been developed. This paper presents a new approach for generating the state-space average-value model. In the proposed methodology, the so-called duty-ratio constraint and the correction term are extracted numerically. The parasitic effects of circuit elements are really included based on state-space averaging. The model is implemented in Simulink and the transient response and open loop transfer functions are simulated. Numerical analyses and experimental measurements confirm that the new models are more accurate than previous models.
