A DC-DC buck-boost converter is operated with the continuous current mode. If the input voltage is 50 V and the duty cycle of the switch is 0.6, the output DC voltage is

Right Answer is:

75 V

SOLUTION

Given,

Input Voltage (Vin) = 50 V

Duty Cycle (D) = 0.6

The output voltage equation of the buck-boost converter is

Vout = (D × Vin)/(1 − D)

Where

D = Duty cycle

Vin = Input Voltage

Vout = (0.6 × 50)/(1 − 0.6)

Vout = 30/0.4

Vout = 75 V
