“…There were four redundant pumps and two redundant sets of pumping loops and control electronics. In 2014, the TTCS reached its expected lifetime [6]. In order to continue functionality and improve the cooling of the Tracker, a new Upgraded Thermal Pump System (UTTPS) was designed and built.…”

The Alpha Magnetic Spectrometer (AMS) is constantly exposed to harsh condition on the ISS. As such, there is a need to constantly monitor and perform adjustments to ensure the AMS operates safely and efficiently. With the addition of the Upgraded Tracker Thermal Pump System, the legacy monitoring interface was no longer suitable for use. This paper describes the new AMS Monitoring Interface (AMI). The AMI is built with state-of-the-art time series database and analytics software. It uses a custom feeder program to process AMS Raw Data as time series data points, feeds them into InfluxDB databases, and uses Grafana as a visualization tool. It follows modern design principles, allowing client CPUs to handle the processing work, distributed creation of AMI dashboards, and up-to-date security protocols. In addition, it offers a more simple way of modifying the AMI and allows the use of APIs to automate backup and synchronization. The new AMI has been in use since January 2020 and was a crucial component in remote shift taking during the COVID-19 pandemic.

“…The magnitudes of the secondary line voltages (VA 1, VB 1, and VC 1 and (VA2, VB 2, and VC2) should be equal to each other to result in a symmetrical system and to reduce the ripple in output DC voltage . The phasors of the voltages produced by the autotransformer V A1 , V B1 , and V C1 were at +15 • with respect to the supply voltages V R , V S , and V T , while the other set of the phasors of the voltages V A2 , V B2 , and V C2 were at −15 • with respect to supply voltages, resulting in a 12-pulse rectification [9,30,31]. The magnitudes of the secondary line voltages (V A1 , V B1 , and V C1 and (V A2 , V B2 , and V C2 ) should be equal to each other to result in a symmetrical system and to reduce the ripple in output DC voltage .…”

“…Lower current harmonic content and higher power factor are achieved by using interphase transformers and impedance-matching inductors, which, in contrast, result in increased complexity, volume, weight, and cost [3]. Moreover, these components may suffer from detuning [3][4][5][6][7][8][9]. To improve the quality standards and reduce the overall size, AC-DC converters having a higher pulse number have been proposed [1][2][3].…”

In this paper, a conventional 12-pulse transformer unit (CTU) and an autotransformer 12-pulse transformer unit (ATU) are compared in the view of the RTCA DO-160 standard for aircraft applications. The design of the magnetic components is proposed via a coupled FEM-circuital analysis in the time domain for an 800 Hz/2 kW system. Input AC distortion, power factor, and output DC ripple are evaluated through simulations. An accurate power loss analysis is carried out, taking into account copper losses, magnetic losses, and power losses due to power switches. The reduction in the size and weight of the ATU with respect to the CTU solution is discussed, including the need for filtering systems and the standard requirements.
