The DC/DC converter is the core part of the two-stage electric vehicle Onboard Charger.At present, the phase-shifted full-bridge soft-switching DC/DC converter has problems such as difficulty in commutation of the lagging leg, voltage fluctuation on the secondary side of the transformer, and low efficiency.A full-bridge DC/DC converter with two cla
Although acute leukaemia is rare in pregnancy its importance lies in its life-threatening potential, both to the child and the mother.The possibility of vertical transmission of leukemic cells increases the attention devoted to these patients and their offspring.Three cases of pregnant Food Service young women (15-17 years of age) with AML are pres
Abstract Background Highly pathogenic avian influenza (HPAI) H5N1 virus is entrenched in poultry in Asia and Africa and continues to infect humans zoonotically causing acute respiratory disease syndrome and death.There is evidence that the virus may sometimes spread beyond respiratory tract to cause disseminated infection.The primary target cell fo
This work proposes a CMOS reconfigurable charge pump (CP) for a low-voltage energy harvesting system.It utilizes the low effective resistance from the parallel CP to enhance its power conversion efficiency (PCE).The CP exhibits an adaptive configuration with different stages depending on the input voltage, changing its voltage conversion ratio (VCR
The article investigates vibration and noise protection devices for wheeled vehicles using dynamic vibration absorbers (DVA).Algorithms for modeling their dynamic characteristics based on adaptive calculation schemes are presented.A non-linear suspension Cupcake and Cake Boxes with DVA and a noise-absorbing partition is considered, which is due to
