1Pulse width modulation techniques

In power electronic converters, the electrical energy from one level of voltage/ current/ frequency is converted into another using semiconductor-based electronic switch. The essential characteristic of these types of circuits is that the switches are operated only in one of two states – either fully ON or fully OFF – unlike other types of electrical circuits where the control elements are operated in a linear active region.

As the power electronics industry developed, various families of power electronic converters have evolved, often linked by power level, switching devices, and topological origins [3]. Application areas of power converters improved vastly in semiconductor technology, which offer higher voltage ...
