This paper presents a study of a processes in the three-port converter under different modes of operations. Circuit topology provides a compact size of the device, allows to get zero pause and decrease losses. The modeling reflects the experimental results.
An approach based on the electromagnetic topology method for predicting immunity to disturbance of aircraft electronic equipment at the influence of intentional ultrashort electromagnetic impulses is discussed. Aircraft for small aircraft a fuselage and tail, which are made of composite material, are considered. An example prediction of electromagnetic interference in coupling path of interface and...
The report is dedicated to the closed-loop design for a phase locking and a magnitude balancing of the three-phase inverter voltages to the three-phase grid voltages when the AC motor stator windings are switched to the AC power supply from the power frequency converter and backwards. The proposed control strategy for the AC drive with IGBT-inverter allows to decrease an inductance of current-balancing...
The use of adaptive estimator based on the flux linkage algorithm gives an opportunity to eliminate the speed sensor and rotor position sensor and to reduce the mass and dimensions parameters of the drive. Estimator provides the actual values of back electromotive force of the synchronous machine and that makes it possible to apply permanent magnet synchronous machine efficiently. The article presents...
General weaknesses of the existing medical exoskeletons were described in this article. Design issues of new modular medical exoskeleton with electromechanical drive were considered. Design results of active knee joint exoskeleton with field-oriented control were submitted.
In this paper dynamic properties of resonant converter with ZCS (Zero Current Switching) were proposed. Closed-loop control system and “control action — output voltage” transfer function was obtained.
