ABSTRACT
This article gives an overview of the main passive solutions and active techniques, based on AC switches
to limit inrush currents in medium power AC-DC converters (up to 3.7 kW) for electric
vehicle charging systems. In particular, a strategy, based on SCR (silicon
controlled rectifier) phase, shift control in a mixed
rectifier bridge with diodes and thyristors, is proposed. The challenge is to help
designers optimize the triggering delay of SCRs to both limit the peak value of
inrush current spikes and optimize the charge duration of the DC-link capacitor.
A mathematical model (Mathcad engineering tool) has been defined to point out, the interest of a variable
triggering delay to control SCRs to meet the expectations described previously.
Experimental measurements using an industrial evaluation board of the AC-DC converter
demonstrate the robustness of the method.
