A Regulated High Voltage Power Supply (RHVPS) and its results are presented for its initial integration and operation with LHCD system. Experimental results are shown to show the ability of RHVPS as a practical source of electrical power for LHCD. Klystron is operated at 3.7 GHz. with a continuous wave (CW) RF power level of 500 kW with various subsystems. RHVPS has proven its capability for feeding...
A positive ion neutral injector capable in delivering 5MW (55kV, 90A) ion beam power is being operated for SST-1 neutral beam injection (NBI). SST-1 Neutral beam injection systems has various components on beam line like ion source, neutralizer, deflection magnet, ion dump, beam dump etc. A Thermocouples based diagnostics is being used for Power density distribution, Beam alignment and System protection...
The Neutral Beam Injector of SST-1 (Steady-state Superconducting Tokamak-1) uses Filamented Ion Sources with AC heating. A regulated filament power supply is essential to maintain constant filament temperature, beam current and plasma. This paper presents the design and performance of AC-to-AC converters for the filament power supply system. A 24 phase heater supply is used to minimize the ripple...
Regulated high-voltage power supplies (RHVPSs) are important power sources in high-power heating and current drive systems for a tokamak. Along with high power at output, these power supplies meet the requirements of fast dynamics (on the order of few microseconds), low ripple factor, and good output regulation. A development overview is presented for RHVPS ranging from 14 to 80 kV at several-megawatt...
Regulated High Voltage Power Supplies (RHVPS) are developed at the Institute for Plasma Research (IPR) for Neutral beam and RF heating applications of Steady-state Superconducting Tokomak (SST-1) up to 80 kV, 130A rating. They deliver power to loads that have very low fault energy tolerance; thereby protection of load is mandatory. At each stage special diagnosis is necessary to protect power supply...
Regulated High Voltage Power Supplies (RHVPS) are major components of any high power heating and current drive system for a Tokomak. A typical RHVPS need to have fast dynamics, good ripple and regulation performance and most importantly μS order fault clearing time.
