Chapter 10

Power Electronics

The electric power grid must operate at fairly constant voltage and fixed frequency to ensure that all generators are synchronized and that the entire system is stable. If any generator produces voltage or frequency different from the rest of the system, blackouts can occur as discussed in Chapter 14. Because of this limitation, all electrical devices and equipment were designed to operate at the voltage and frequency of the utility’s feeders. Accordingly, they were limited in performance, heavy in weight, and inefficient in operation. With the development of power electronic devices and circuits, the newer apparatuses and equipment have electronic converters that allow users to change the voltage and frequency applied ...
