PW1: New converter structures

Practical work with DC-DC and AC-DC converters involves hands-on experience with designing, building, and testing these essential power electronic circuits. DC-DC converters are used to transform a direct current (DC) voltage from one level to another, which is crucial in applications like portable electronics and renewable energy systems. They operate using switching techniques, allowing for efficient step-up or step-down voltage conversion. Common types include buck, boost, and buck-boost converters, each with its own application depending on the required output voltage relative to the input.

In contrast, AC-DC converters, also known as rectifiers, convert alternating current (AC) to a stable DC output. This is typically achieved through rectification of AC power from the grid or other AC sources. Practical work with AC-DC converters involves understanding different rectification methods, such as half-wave and full-wave rectification, and implementing filters to smooth the output voltage. Both types of converters are vital in modern electronics for ensuring efficient and reliable power supply to various devices and systems. Practical experiments often involve simulating these converters using tools like MATLAB Simulink to analyze their performance under different conditions.
