"Closed Loop Input and Output Impedances of DC DC

This work derives the closed loop input and output impedances of three major types of DC DC converters (Buck, Boost, and Buck Boost) operating in voltage or current mode control. First, it introduces the small signal converter model employed to derive the input and output impedances. Next, it reviews open loop impedances for use in simplifying the expressions developed for closed loop impedances.

Performance analysis of using mine water from an abandoned

for heating and cooling purposes using open loop or closed loop systems. In this paper, the use of mine water from a flooded coal mine for heating of buildings is presented using a GSHP system with an open loop configuration. The novelty of this approach is that a single shaft is used to extract the warm water and inject the cooler water back into
