Switch Mode Power Supply Design Constraints for Space Applications

This paper describes the design trade-offs presented in DC-DC power converters used in space applications. The major concern, in the design of power supplies for space applications, is to obtain a very high reliability level, which can be very difficult to quantify, considering the relatively low production quantities involved. Space converters have to deal with radiation effects, vacuum enviro...

Effects of Quantization on Digital Buck Converter Switch Mode Power Supply

The development of power supplies has evolved from using linear or series regulator to switch mode power supplies (SMPS). Nowadays, SMPS have employed the use of digital controllers such as microcontrollers and digital signal processors (DSP’s) to provide compensation, housekeeping, fan control, communication, etc. The main advantages of using a digital controller are: insensitivity to environm...

Power-saving transportation mode identification for large-scale applications

Transportation mode detection with personal devices has been investigated for over ten years due to its importance in monitoring ones’ activities, understanding human mobility, and assisting traffic management. However, two main limitations are still preventing it from large-scale deployments: high power consumption, and the lack of high-volume and diverse labeled data. In order to reduce power...

A design of Rectangular Waveguide TM11 to TE10 Mode Converter for S-band Applications

A design of a compact, easy to fabricate and applicable structure rectangular waveguide TM11 to TE10 mode converter is presented in this paper. The design procedure of the proposed structure can be divided into two parts in sequence. The beginning one is dedicated to the transformation from TM11 to TEM mode using a central conductor, while the second part is the transformation from TEM to TE10 ...
