A conventional Flyback converter's controller is based on the primary side of coupled inductor-requiring isolated coupling for both output voltage measurement and any synchronous rectification gate signal. novel communication approach proposed here, whereby need such signal eliminated by moving to secondary communicating back switch through inductor itself. This simultaneously allows direct access voltage, reduced component count, rectification, soft turn-on without optoisolator propagation...
Power line communication (PLC) in automotive traction batteries is considered an attractive alternative to the serial-bus used state-of-the-art battery management systems (BMS). PLC uses power as medium and saves additional wires, connectors isolation effort. In this work, we present a proof of concept for small-scale pack. From hardware approach, develop modem, which modulates UART data using on-off-keying (OOK) couples it onto line. To test PLC, design demonstrator consisting two modems...
This paper presents an analysis of a novel control approach for the secondary side controlled flyback concept, along with improved drain-source voltage sensing more precise gate signals and reduced losses. In contrast to existing scheme this presented here sustains constant switching frequency throughout load range without any additional hardware, boosting efficiency simplifying coupled inductor design optimization. A 65-W demonstrator shows minimal output ripple during changes, peak 89.90%,...
Abstract Electric vehicles (EVs) are without a doubt one of the hottest topics our time because their advantages over combustion engine vehicles. This has persuaded many developers to try improving EVs so they will be more reliable and cheaper as result suitable for broader range consumers. In this paper we dive into proper way measuring understanding impedance prismatic cell from 100 kHz up 1 GHz. Some common measurement mistakes important points notice also explained. The effect power bar...
This paper explains the proper way of measuring a prismatic li-ion battery cell which is used in electric vehicles. The challenges and solution connecting to vector network analyzer are discussed. It shown how properly measure, calculate de-embed parasitic components medium connector. At end measured wide frequency range from 1MHz 1GHz.
