An improved compensation alternating voltage regulator using bidirectional-thyristor bridge
High power alternating voltage regulators commonly use few isolation transformers to compensate the variation of the input voltage or output load, and use a bidirectional-thyistor bridge with multiple arms to adjust the direction and magnitude of the compensation voltage . This kind of voltage regulator has been widely used for its simplicity, low cost, and high efficiency. But its compensation voltage adjustment process often accompanies with deep output voltage sags or high input current overshoots. An improved topology is proposed---adding one more circuit unit to help the adjustment of compensation voltage. The improved topology can adjust the compensation voltage smoothly---having neither output voltage sags nor input current overshoots.
