一种用于感应加热器的移相控制直接交流-交流变换器

This paper proposes a new control method of a direct ac-to-ac converter consisting of two half-bridge converters and a series-resonant circuit. This circuit converts the ac input power from the utility grid to a high-frequency ac output without any dc stage. This circuit does not require a diode bridge rectifier and, thus, makes it possible to reduce forward voltage drops and power losses in the d...
