The ITER Ion Cyclotron Heating and Current Drive system (IC H&CD) is designed to deliver 20MW a broad range of plasma scenarios between 40 55MHz, during very long pulses. It consists two broadband equatorial port plug antennas, their pre-matching matching systems, transmission lines, Radio Frequency (RF) Sources High Voltage Power Supplies. overall project schedule has been revised agreed by Council; it re-integrates the second antenna its power supplies in construction baseline sets dates...
The ITER ion cyclotron heating and current drive system is designed to deliver 20 MW a broad range of plasma scenarios, during very long pulses (∼500 s in inductive, up 1 h noninductive, scenarios). associated radio-frequency (rf) source has be compliant with all operation modes foreseen operation. India responsible for delivering the rf package ITER, which includes one prototype followed by eight bulk production units. This lecture presents system, design considerations, status research...
This paper includes a detailed study of Zero Voltage Switching resonant converter based buck converter, understanding with the help mathematical equations for various modes and simulation DC Power source at different voltages current level. As in conventional pulse width modulated (PWM) power converters, switches have to cut off load within turn-on turn-off times under hard switching conditions. The concept is incorporate tanks converters create oscillatory (usually sinusoidal) voltage...
This article comprises a design, simulation, development, and testing of 500-V, 4-A dc power supply based on the zero voltage switching (ZVS) scheme. Resonant converters have many variants. In this article, quasi-resonant converter (QRC)-ZVS-half bridge-constant frequency type has been used which is generally employed for fixed load application, but in proposed novel tank circuit designed such way to keep ZVS instant intact even case variable conditions. Four modules resonant buck 125 V, 4 A...
The high-power radio frequency source for ion cyclotron heating and current drive of ITER tokamak consists two identical 1.5 MW amplifier chains. These chains will be combined using a wideband hybrid combiner with adequate coupling flatness, phase balance, return loss, isolation response to generate 2.5 (RF) power in the range 36 60 MHz. As part in-house development program at ITER-India, flatness loss/isolation better than 0.4 −25 dB, respectively, has been simulated. A detailed analysis...
