Magna-Power 向美国海军交付 1 MW 水冷式 MagnaLOAD 直流电子负载
Magna-Power Electronics, a leader in programmable power products worldwide, is proud to announce the delivery of a 1 MW water cooled DC electronic load to the US Navy, which will be used to research, develop, test, and evaluate the operation of energy storage modules (ESMs) in a shipboard environment. To meet this requirement, Magna-Power delivered ten (10) of its standard 100 kW WRx Series MagnaLOAD DC electronic loads, configured in two master-slave sets of 500 kW.
The 500 kW DC electronic load systems will be part of a real-time hardware-in-the-loop (HIL) simulator, which will drive the MagnaLOADs using its high-speed analog input. A digital simulator will be used in place of the actual electric shipboard equipment to conduct model-based simulation of the shipboard electric load. The MagnaLOADs will mimic discharge profile of the ESM, depending on the components under test and the model being simulated.
Given the nature of these tests, which can last for days, Magna-Power designed its MagnaLOAD products for continuous full-power operation at 50°C ambient operating temperature and cooling water temperature up to 25°C. Microchannel water cooled heatsinks were designed and are manufactured by Magna-Power, allowing the company deliver power dissipation of 12.5 kW per 4U. In addition, Magna-Power’s new patented Active Resistance Technology (US Patent 9,429,629) combines a switched binary matrix of resistances with MOSFETs to deliver features and performance consistent with traditional electronic loads, at a fraction of the price. The product features a wide operating range, allowing full power to be achieved over the range 50% to 100% rated voltage in its high power range. A separate low power range enables high current operation at lower voltages.
“While a significant engineering undertaking for the company, the result is a brand new product line, three new product series, and a new robust digital control scheme that will be far-reaching,” said Ira J. Pitel, Ph.D., President of Magna-Power Electronics. He continued, “as a company, we are very proud to support this program and greatly value the US Navy’s support and cooperation to allow Magna-Power to realize this system.”
该合同是 Magna-Power 全新分布式 DSP 数字控制平台 MagnaLINK™ 的试验场，为公司未来产品铺平了道路。这一全新控制平台适用于 MagnaLOAD 产品线，可在高电磁干扰环境下同时实现 40 个模块的高速、高可靠性控制和测量聚合。此外，MagnaLINK 支持同步主从固件升级，具备新产品配置检测和自动设置重新配置功能。
ESM 完全开发后，计划集成到舰船电气系统中，根据舰船的电力需求动态充当电源或功率吸收装置。MagnaLOAD 直流电子负载产品线现已上市，涵盖三 (3) 个产品系列的多种风冷和水冷型号。
