DESIGN OF A.C.-D.C. CONVERTER USED IN PROTECTION
ELECTRONIC DEVICES OF LOW VOLTAGE
THREE-PHASE INDUCTION MOTORS
In this paper presents the design of a.c.-d.c. converter used in
protection electronic devices of low voltage three-phase induction motors. The
main parts of converter are: current transformer, precision full-wave rectifier
and low-pass active filter.
