The high frequency voltage oscillation on the DC/DC gate driver of a H-bridge created during the turn-off intervals of the power switches has critical impact on component reliability and control quality. This noise can propagate freely in the low power plane to other functional circuits of the converter due to the performance degradation of EMI filter in high frequency range above 30MHz. In this paper,...
Connecting legs in parallel in a buck convertor is a way to increase the output current by improving the output's waveforms. By coupling these legs, it is possible to reduce the current ripple and thus the coil volume; however this coupling adds internal variables which must be controlled in order to prevent saturation of the iron core in the couplers and keep the linearity of the system. This paper...
A digital integrated circuit for sub-nanosecond dead-time adjustment is designed and its operation principle is described. The designed dead-time adjustment circuit (DTAC) generates two complementary control signals for the FET switches used in synchronous switching DC-DC converters. The control signals are generated from a PWM signal that is provided at the input of the DTAC. The circuit is based...
In a world with an accelerated population aging, there is an increasingly interest in developing solutions for the elderly living assistance. The Internet of Things is a new reality that is completely changing our everyday life, and promises to revolutionize modern healthcare by enabling a more personalized, preventive and collaborative form of care. Aiming to combine these two important topics, this...
In order to connect existing electronic devices that are equipped with fieldbus communication capabilities into the emerging Cyber Physical Systems (CPS), new models that combine live data from the underlying devices together with the metadata information that describes them have to be created. The new solutions should be based on widely accepted communication standards and should be easy to implement...
Industrial Internet of things (IIoTs) relies on different devices working together, gathering and sharing data using multiple communication protocols. This heterogeneity becomes a hindrance in the development of architectures that can support applications operating independently of the underlying protocols. Therefore in this paper, we proposed a modular and scalable architecture based on lightweight...
