A Study on the Inverter-Excited Induction Generator

인버어터 여자에 의한 유도발전기의 연구

An inverter-excited induction generator is discussed in this paper. A brief review of the capacitor-excited induction generator is given and the steady state characteristics of the induction generator excited by an inverter are evaluated. It is shown that the output voltage of the system can be controlled by adjusting the slip, for given operating conditions. The introduction of feedback control makes it possible to control the output voltage stably over the wide range of speed and load. Experimental results are given. The output of the induction generator is then converted into a CVCF(Constant Voltage-Constant Frequency) power source using a PWM inverter with simple control circuit.
