In the past few years, modular multilevel converter (MMC) has seen extensive application in high voltage sector. The MMC is composed of multiple similar submodules (SMs). order to ensure optimal functioning Modular Multilevel Converter (MMC), it imperative maintain a balance between voltages upper and lower arms capacitor. Additionally, essential suppress alternating current (AC) components circulating current. Due complex interdependence equations governing dynamics MMC, control systems...
At the Institute for Plasma Research (IPR), Gandhinagar a 2 MVA ac/dc accelerator power supply (APS) unit was installed powering neutral beam injector (NBI) to be used in Nuclear Fusion Power Research. The APS is based on 12-pulse converter system consisting of 1.914 MVA, 11 000/541.86/541.86 V transformer and two six-pulse rectifiers connected parallel. feeds 3 nos. high frequency inverters (400 Hz) which are voltage rectifier-transformers (HVTRU) producing dc at output. First, rectifier...
High-Voltage DC power supplies are required for the injection of charged particles into accelerators or cluster ions fusion devices to heat plasma and drive current. The typical voltage HV is in range several kilovolts currents hundreds milli-amperes. Though many technologies available commercial HVDC system, unique requirements system above mentioned applications have some parameters which cannot be met by technologies. low ripple output voltage, good regulation, less stored energy. This...
A high voltage, frequency transformer unit has been designed and built for powering the Cockcroft–Walton voltage multiplier to be used as part of a particle accelerator power supply at Institute For Plasma Research, India, nuclear fusion research facility. novel combination (25 kV), (20 kHz), (70 kV A) specifications makes its design distinctive more challenging. The complete is composed two 0.350/25 amorphous core transformers connected in center-tap configuration immersed an oil-filled...
