This paper presents research results related to the concept of a high-voltage-gain DC-DC converter with low input current ripple. In proposed topology, low-volume switch-mode boost operates in parallel switched-capacitor voltage multiplier (SCVM). The overall achieves four-fold gain, but stress transistor and diode is only half output voltage. achieved by applying specific topology converter. F...

Abstract We examine the possibility that fast radio bursts (FRBs) are emitted inside magnetosphere of a magnetar. On its way out, wave must interact with low-density e ± plasma in outer at radii R = 10 9 –10 cm. In this region, magnetospheric particles have huge cross section for scattering wave. As result, strongly interacts and compresses it, depositing FRB energy into compressed field scatte...

Abstract To explore the sensitivity sorting of a one-dimensional performance prediction model, high-load centrifugal compressor is studied. Using Latin Hypercube method, influencing factors model are designed. Based on analysis ANOVA, main pressure ratio and efficiency investigated, guidance for optimization proposed. The results show that affecting deviation loss, radial diffuser incidence imp...
