Question 1. Derive an equivalent circuit that models the dc properties of this converter. Include the loss elements listed above, but ignore all other sources of loss. Your model should

correctly describe the converter dc input port. If necessary, manipulate your model into the form shown below. The quantity IL is the dc component of the magnetizing current, referred to the primary. For questions 1 to 4, you are asked to enter mathematical expressions for the elements in this model. The effective turns ratios are functions of only the duty cycle D and transformer turns ratio n, while the effective loss elements Re and Ve may be functions of n, D, and the loss elements, but no other quantities. Question 1: Enter your expression for the effective turns ratio m1 in the field below.
