مستخلص المنشور

A discrete-time model for pulse-width modulated (PWM) converters operating in the discontinuous capacitor voltage mode (DCVM) is formulated. It leads to the exact discrete-time mathematical representation of the values of the output and internal signals. A one-cycle-average (OCA) discrete-time model is introduced. This model provides the exact discrete-time mathematical representation of the averaged values of the output signal. This model also provides the average values of other internal signals with little increase in simulation time. Numerical simulations show the accuracy and speed of the proposed method.
