WebThe buck converter is a type of switch-mode power supply that is designed to convert electrical energy from one voltage to a lower one. The buck converter operates with a series connected switching transistor. As the duty cycle, D < 1, the output voltage of the buck is always smaller than the input voltage, VIN. WebSo the buck-boost converter steps the voltage downwhen the duty cycle is less than 50% (i.e., Ton < Toff), and steps it upwhen the duty cycle is greater than 50% (Ton > Toff). But note that the output voltage is always reversed in polarity with respect to the input Š so the buck-boost converter is also a voltage inverter. When the duty cycle is
