Customisable high-current power control solution with liquid cooling

Advanced Energy Industries, Inc. has announced its Thyro-PX Modular Solution, a fully configurable, distributed architecture that allows operators to build custom power control with liquid-cooled high-power stacks and external control units to meet precise requirements.

The components are designed to meet glass manufacturing requirements, arc furnaces, rectifiers, and other high-current heating elements. Configuration options include separating control and power functions to minimise EMC issues.

The solution's silicon-controlled rectifier (SCR) technology optimally controls temperature and power. It delivers precise phase angle control and improved efficiency while lowering costs and CO2 emissions compared to standard thyristors.

"Thyro-PX Modular Solution is built on proven SCR technology and offers unparalleled flexibility in high current applications to simplify switching from gas-fired systems to cleaner electrically generated heat," said Dhaval Dhayatkar, Advanced Energy's vice president, Critical Sensing and Control Products, System Power. "Thyro-PX provides the components customers need to quickly configure and build high-efficiency, high-current, liquid-cooled power stacks to their exact specifications – reducing installation complexity, cost and the overall system footprint."

Each Thyro-PX control unit can drive up to three high-power water-cooled Thyro-PX stacks, increasing current delivery capability. The solution easily integrates with common field bus systems, attaining a current accuracy of 0.5%. It has simple AC and DC configurations and a wide voltage range of up to 690VAC (750VDC), with 1,000VAC available on demand.

Communication between the control and power stacks is managed through an optional fibre optic trigger interface card, which delivers precise isolation between the control and power sections. Further components in the Thyro-PX Modular Solution include voltage transducers, impulse converters, and releasing modules.
