Generator self excitation
WebWe know that a self-excited motor is one of the types of DC generator which is available in three different types like compound generator, shunt generator, and series generator. The classification of DC generators can be done based on … WebThat's how most conventional home generators operate. Note that there is a separate class of inverter-generators, in which alternator output is rectified and then converted back to AC by an electronic circuitry. In such devices RPM is variable. SELF EXCITATION At a fixed speed, the V out can be control only by varying the field strength. A ...
