Abstract :
Voltage source flyback converters in the discontinuous conduction mode with a new control strategy is presented in this paper, that is capable of operating over a wide range of input and output voltage variation. Over the normal range, pulse width modulation at fixed frequency is used as in conventional system. At low duty cycle demands, constant pulse width with variable frequency is used to extend the effective duty cycle range
