In a PWM Buckboost converter Vin 12 V The switching frequen

In a PWM Buck-boost converter, V_in = 12 V. The switching frequency f_s = 200 KHz, and the maximum of the ramp signal is theta_r = 2 V. Calculate and draw the control signal V_c associated with the V_0 = 18 V. What are the methods to control the output voltage with (Assuming the magnitude of the ramp signal is fixed.)

Solution

Ans) a) Yes procedure and answer is correct Control voltage Vc=1.2 V

b) The output voltage can be controlled by pulse width modualation PWM ,in this by changing the control signal which inturn changes duty ratio and hence output voltage is changes according to the that
