Presentation of a Modern Method in Teaching Modeling and Converting PWM Switches of DC-DC Converter

Modeling and converting way of PWM-switch is a simple way in modeling and converting PWM of DC-DC convertor in a continuous space state. The main advantage in presentation of this way is the adaptability and simple usage of this way in comparison with other ways. The main idea in this paper is the replacement of switches with their time-averaged models. Also, this way presents a way in which convertor model created the same result of status space average way considering the non-linear effects. At first, the total principles is gained for determining the switch in which the branches flow and nodes voltage is proportionate with average amount of voltages and main flows. In teaching how to use this way, we can find out that this model is able to consider the agitation effects and components of second-order equation which lead to being non-linear that this fact can be used in circuit-based simulation. This model is a strong tool that can be used for simulating transient and lasting status.
