Plasma & Particle Physics Magnet Power Supplies
TT Series
This dedicated range of high stability DC and AC power supplies for critical duty industrial science laboratory applications for plasma physics, particle accelarator, nuclear and space research. The systems can be manufactured as single units, or in modules that can be assembled to form a fully integrated complete system for use in important turn-key major plasma and particle physics projects.
Transformer Rectifier
This power product enables a cost effective means of providing power supplies of more than 1,000kW for large magnets where high accuracy of current control is required. The rectifier systems use input isolation transformers connected to fully controlled 6 pulse, 12 pulse and 24 pulse thyristor switching bridges. The output stage is provided with a passive output filter as standard and a supplementary active filter is added so the ripple level in the DC can be reduced to a very low level as determined from the accuracy of the current and voltage regulation required by the application. The output from the rectifier can be soft started to ramp up from 0 to 100% over a pre determined time to suit the energy required by the magnet.
High frequency switch mode
This is a modular concept of power system with an input stage with low harmonic distortion and high power factor when connected to the input mains. The second modular stage converts the AC to DC, the output stage incorporates a high frequency DC to DC converter with galvanic isolation transformer feeding a second DC output stage for connection to the load through interconnecting busbars.
The modular power supply system is built from pre engineered input stage with power factor and harmonic correction, DC intermediate module, output power module and control unit module as subassemblies all combined into an industrial rack to produce an integrated power system. The rack can be delivered as a single system and can include redundant modules (n + 1) if required. The power system rack can be combined with similar multi module power racks to supply magnets in excess of 20,000 Amps with very accurate controlled current regulation and step less adjustment from 0 to 100% output.
The high frequency power supply system is designed for use with magnet loads that require DC with low ripple content better than 100 p.p.m current controlled power source and where the connected load requires an instantaneous response to the reference control signal.
This type of power supply system is fitted with a sophisticated microprocessor control system for the command, protection and operating logic and for the monitoring and diagnostic facilities interface with the laboratory computers.
The logic used in the high frequency power systems enables us to configure the system operating elements of the power sub assemblies to deliver a precise power output or configured to enable the power sub assemblies to produce a bi-polar output for other types of magnet loads.
