High-stability, Current-controlled, Card-based, True-bipolar, Switch-mode Power Converter for Electromagnets

Overview

High-stability, Current-controlled, Card-based, True-bipolar, Switch-mode Power Converter for Electromagnets

This is a high-stability, output-current-controlled, switch-mode, true-bipolar power converter for electromagnet. The power converter is capable of delivering output voltage (up to ±50 V DC), output current (up to ±15 A DC), and output power (up to 600 W) ratings with minimum alterations. It operates from 60 V max dc input source. The power converter is developed on a single 6U four-layer PCB, complete with power circuit, control electronics and interface electronics for its remote operation. It is equipped with precision current sensor, electronics and on-board constant-temperature bath that provides output current stability within +/- 100 ppm of the full-scale current (for 8 hours after 1 hour of warm-up). It is capable of being operated in both the polarities of output voltage and current, with smooth zero cross-over. Important signals are available on the front panel facilitating in-situ diagnosis/monitoring of the operational status.

FACILITIES REQUIRED

Standard facilities available with a manufacturer of electronic systems such as PCB manufacturing, component soldering, standard mechanical shop floor for assembly etc. are necessary for production. Some of the items (e.g. magnetic components, heatsinks etc.) can also be sub-contracted by the industry if the related infrastructure is not available under the same roof. However, the manufacturer desirous of acquiring the technology should have a complete in-house board assembly facility following IPC 610. Standard test and measurement equipment (meters, oscilloscopes etc.) are sufficient. Various sources of precision meters and sensors are commercially available for the manufacturer to augment the infrastructure.

Who Should apply


Interested parties with Engineering & Scientific knowledge, good financial background and adequate experience of products manufacturing & fabrication with technical capability in the area of interested technology and having or interested in setting –up facilities for production would be preferred.
