Experiments have been conducted on a dual electric grid thermionic device to investigate an alternative method of space charge mitigation in a thermionic energy convertor (TEC). Two electric grids, the attractor and deflector grids, provide opposing electric fields to overcome space charge while minimizing power losses to the attractor grid. Electron beams are formed in the electrode gap provid...

In this paper, Threshold Inverter Quantizer (TIQ) is a novel idea which can effectively replace the reference voltage generator, resistive/capacitive divider network and array of differential comparators in conventional flash Analog to Digital Converter (ADC) by an internal comparator constructed Complementary Metal Oxide Semiconductor (CMOS) inverters. The inverter threshold serving as voltage...

A simple, topology-independent method is proposed for simulating the responses of open and closed-loop quasiresonant DC-DC convertors operating in the zero-currentswitching mode (ZCS-QRC). The method hinges on the substitution of the resonant network and switch assembly, fundamental in the realisation of such systems, by an equivalent circuit which represents its average behaviour. This permits...

Generation of circularly polarized (CP) light with high purity and intensity was achieved using a single-, parallel, multi-layered luminescence-based CP convertor composed linearly luminescence (LPL) film quarter-wave plate.
