2. A forward converter design is required. The isolated single transistor forward circuit has been chosen. The design parameters are: Input voltage = 240V Output voltage = 24V Output current = 10A Switching frequency = 10kHz Output current at threshold of continuous current = 2A Two possible designs are to be evaluated: Design A for which the duty cycle is 0.1 Design B for which the duty cycle is 0.4 The effects of transformer magnetising current may be neglected in all design calculations. a) Draw the circuit diagram, using the dot convention to show the relative polarity of any wound components and determine the required turns-ratio of the transformer for each design. 2.
