| Abstract |
Use of a series transistor array in an AC voltage regulator could substantially reduce the weight and volume and also lower the manufacturing costs by eliminating special transformers (in ferro-resonant systems) and servo mechanisms (in servo driven auto transformers). This non-switching analogue technique has advantages over thyristor driven tap change systems too. This basic technique could be further improved to achieve higher overall efficiency, higher power ratings and to achieve a harmonic and spike free sinusoidal output. The article outlines the proposed circuit enhancements for a bipolar power transistor array technique for achieving a clean sinusoidal output with high overall efficiency. |
