The prototype uses two low power modules and a ferrite combiner to add the voltage and power at the output. The prototype design is attempted with Class-E amplifier topology where a MOSFET is switched resonantly. A conceptual design for a 200 kW, 1 MHz power supply and a prototype design for a 600 W source been done. In terms of Power Electronics, thermal and power coupling issues are major challenges at such a high frequency. Switching converter based topology used to generate 1 MHz sinusoidal output is expected to have advantages on efficiency and reliability as compared to traditional RF Tetrode tubes based oscillators. The Ion Source for a Neutral beam Injector at ITER-India uses inductively coupled power source at High Frequency (âˆ❁ MHz). High Frequency Power supply (HFPS) is used for various applications like AM Transmitters, metallurgical applications, Wireless Power Transfer, RF Ion Sources etc. Gajjar, Sandip Thakar, Aruna Patel, Amit Raval, Bhavin Dhola, Hitesh Dave, Rasesh Upadhay, Dishang Gupta, Vikrant Goswami, Niranjan Mehta, Kush Baruah, Ujjwal (author)ĭesign of 1 MHz Solid State High Frequency Power Supply This paper describes the conceptual design of a 200 kW power supply and experimental results of the prototype 600 W, 1 MHz source. The output passive network including resonance tuned network and impedance matching network caters for soft switching and matches the load impedance to 50 ohm respectively. The rating of the modules is essentially driven by the maximum power handling capacity of the MOSFETs and ferrites in the combiner circuit. Subsequently solution with class-D H-Bridge configuration have been evaluated through simulation where module design is stable as switching device do not participate in resonance, further switching device voltage rating is substantially reduced. A conceptual design for a 200 kW, 1 MHz power supply and a prototype design for a 600W source been done. The Ion Source for a Neutral beam Injector at ITER-India uses inductively coupled power source at High Frequency (∼ 1 MHz). Gajjar, SandipĪ High Voltage High Frequency (HVHF) Power supply is used for various applications, like AM Transmitters, metallurgical applications, Wireless Power Transfer, RF Ion Sources, etc. Projected operating conditions for a 1MW 450 MHz Klystrode having an overall length of 60 inches and a total tube, circuit, and magnet weight of 250 pounds is presentedĭesign of 1 MHz solid state high frequency power supply Measurements at 470 MHz on existing Klystrodes are given. Efficiencies of this order coupled with potential size and weight parameters which are a fraction of those of existing high power UHF generators open up new applications which heretofore would have been impractical if not impossible. Results on a recent 5-year EIMAC sponsored R and D program which have lead to the introduction of the Klystrode for UHF television and troposcatter applications indicate that at power levels of 1MW or more efficiencies in excess of 75% can be obtained at 450 MHz. There has long been a need for a new more efficient less bulky high power RF power source to drive accelerators in the 200 to 800 MHz region.
