Design of Anode Power Supply of High Power RF Amplifier for Ion Cyclotron Resonance Heating System in EAST

Ion cyclotron resonance heating (ICRH) is a necessary auxiliary heating method in EAST Tokomak nuclear fusion experiment. It is very important to develop a qualified anode power supply for the operation of ICRH system. The anode power supply based on pulse step modulation (PSM) technology was designed. The experimental data show that the design of the anode power supply is reasonable.
