How to simulate a buck converter using PSpice?
At the start a brief and concise introduction of converters specifically buck converts along with their circuit diagram is provided with the explanation of the output they will show. After that the circuits is simulated using PSPICE and the result are compared with the theoretical discussion provided (which should be same).
What is the output voltage of a buck converter?
For the ideal buck converter, any output voltage from 0 V to V. IN may be obtained. In actual DC/DC converter circuits, there are practical limitations. It has been shown that the output voltage is proportional to the duty cycle and input voltage.
How is energy stored in a buck converter?
Since there is energy stored in the inductor, the inductor becomes a source to supply the load by releasing its stored energy. By switching between on-state and off-state constantly, the buck converter is able to decrease the voltage from the input to the output.
What is the difference between a boost and a buck converter?
For the boost converter, V out ≈ 1 / 1 − D V g; for the buck–boost, V out ≈ − D / 1 − D V g, i.e., the buck is a stepdown voltage circuit (as 0 < D < 1), the boost is a stepup, and the buck–boost, with an inverse output voltage, can either step up or step down the line.
What do you need to know about a buck converter?
A buck converter is the one which converts the DC voltage level of an input source to a lower value and shift the current level of the source to a higher value at the output. A simple circuit diagram of a buck converter is shown in the figure below,
How do you save a schematic in PSpice?
After opening the new schematic before jumping into designing first save the schematic by clicking on the file button at the top left corner and then selecting save as so that we can access it anytime in the future. Refer to the figure below,
Where to find the design manager in PSpice?
Open the PSPICE design manager on your PC by typing design manager in the search bar. From the design manager click on the run schematic button to open a new blank schematic as shown in the figure below,
