The Relation between Temperature and Work Function in Thermionic Emission.

Pulsed Thermionic Power Conversion with Positive Work Function Difference

Experimental studies were conducted into the use of nanosecond scale voltage pulses in an inert gas for thermionic power conversion. These studies show that practical materials for the electrodes can provide a positive work function difference when operating in an inert gas environment. Using these materials it has been shown that significant power densities can be achieved. This method of ther...

Encapsulated Thermionic Energy Converter with Stiffened Suspension

This paper reports a prototype of a mechanically and thermally robust encapsulated microfabricated thermionic energy converter (μ-TEC). We used conformal sidewall deposition of poly-SiC to form stiff suspension legs with U-shaped cross sections, which increase the out-of-plane rigidity and prevent contact with the substrate during the heating of the suspended emitter—a qualitative improvement o...

Simulation of Combined Boost Converter Behavior with Positive Output Voltage and Investigation of Voltage Ripple at Output

In this paper, the behavior of a hybrid back-boost converter with a positive output voltage is simulated. This converter consists of an amplifier voltage converter called KY converter and a modified synchronous converter (SR). The converter operates in continuous conduction mode (CCM) and has a non-shock output current, reducing the current stress in the output capacitor and reducing the output...
