Dc chopper شرح
WebThe circuit that is designed to directly convert fixed dc voltage into variable dc voltage is called Chopper Circuit. It is also known as dc to dc converter or dc chopper. Choppers are considered to be dc equivalent to ac transformers, the reason for the same is that similar to the transformers, choppers hold the ability to step up or step down the fixed dc input … WebMar 3, 2024 · In the above waveform, from time period t = 0 to δ T, the chopper is turned ON.Thus from t = 0 to δ T load voltage V L will be equal to source voltage V dc and load …
