RFI EVALUATION OF COMMERCIALLY AVAILABLE ALTERNATOR TYPE BATTERY CHARGING SYSTEMS

Abstract

Two battery charging systems were evaluated to determine the interference levels produced in the RF spectrum from 14 kc to 1,000 mc. The major difference in the two systems is the method of regulation. One makes use of an electromechanical regulator whereas the other is completely transistorized. The radiated interference from both systems exceed the broadband radiated limits specified by MIL-I-16910A. The effect of noise suppression technique on the conducted noise was determined. Techniques used to measure the radiated and conducted noise levels are discussed. The operation of each of the charging systems is also presented.
