Abstract :
The paper presents a new DC power supply based on a two phase induction generator coupled to two series connected transistor power converters. The base drives of the transistors are adjusted so that the power converter can generate the required amount of VAr (lag/lead) to maintain a strictly constant output voltage. The results of studies show that more than the rated power can be extracted from the induction generator at some combinations of terminal capacitance and speed. The load and speed range of the proposed system are derived. For experimental verification, a laboratory type two-phase induction generator was chosen. The results are in good agreement with those obtained from analyses
