Electromagnetic Field Analysis and Design of a Single-Phase
Full-Bridge Power Converter for Electric Vehicle Range Extender 2022-01-5101
This paper takes the single-phase full-bridge power converter of the power
generation system of the free-piston engine of the incremental electric vehicle
(EV) as the research object. By establishing the three-dimensional (3D)
electromagnetic radiation simulation model of the power converter, the
electromagnetic radiation field of the power converter is simulated and analyzed
by using the equivalent excitation source method. The shielding and suppression
effect of the power converter shell on the far-field radiated electromagnetic
field and its influence on the internal electromagnetic field are analyzed. The
shielding cover of the radiation source and sensitive source of the power
converter is designed, and the effectiveness of the electromagnetic radiation
shielding device for shielding the radiation source and sensitive source is
discussed. The simulation results show that the shell of the power converter can
effectively shield the far-field radiation so that the external radiation field
intensity is reduced below the standard value. The designed shielding device of
the radiation source and the sensitive source can effectively reduce the
radiation intensity at the position of the sensitive chip in the near-field area
and satisfy the working conditions of the device.
