Duty cycle boost converter

WebBoost converters are used for generating high output voltages from low input voltages. Such a voltage conversion can easily be done with a switching regulator with a boost topology. However, the voltage gain has a natural limit. The voltage gain is the ratio of output voltage to input voltage. WebThe first step to calculate the switch current is to determine the duty cycle, D, for the minimum input voltage. The minimum input voltage is used because this leads to the …
