【Springer-2013】Digital Signal Processing in Power Electronics Control Circuits
Power electronics circuits are increasingly important in the modern world due to the rapid progress in developments of microelectronics in areas such as micro-processors, digital signal processors, memory circuits, complementary metaloxide-semiconductors, analog-to-digital converters, digital-to-analog converters, and power semiconductors—especially metal–oxide–semiconductor field-effect tran-sistors and insulated gate bipolar transistors.
Specifically, the development of power transistors has shifted the range of applications from a few amperes and hundreds of volts to several thousands of amperes and a few kilovolts, with a switching frequency measured in millions of hertz. Power electronics circuits are now used everywhere: in power systems, industry, telecommunications, transportation, commerce, etc. They even exist in such modern popular devices as digital cameras, mobile phones, and portable media players, etc. They are also used in micropower circuits, especially in energy harvesting circuits.
In the early years of power electronics, in the 1960s and 1970s, analog control circuits were most commonly used, meaning that only the simplest control algo-rithms could be applied. Some years later, in the 1980s and early 1990s, hybrid control circuits were used, which consisted of both analog and digital components. In subsequent years, there followed a slow transition to fully digitalized control systems, which are currently widely used and enable the application of more complex digital signal processing algorithms.
