    摘要： Disclosed is a power supply including an RF power source, a magnetic core transformer including a first transformer and a second transformer, each of which boosts an output of the RF power source. Each of the first transformer and the second transformer includes an input coil, a magnetic core, and an output coil. The input coil includes an outer winding and inner winding. The outer winding and inner winding form a single turn winding, and the outer winding and the inner winding are connected in series to each other.
