CURRENT-LIMITING DC POWER CONVERTER Russian patent published in 1998 - IPC

FIELD: converter engineering. SUBSTANCE: converter has electronic switch controlled in ON-state by trigger pulses and incorporates current limiting provision by suppressing trigger pulses. In order to do without easily implemented low-loss current sensor, DC voltage corresponding to peak value of current is produced by means of additional switch controlled in phase with main current circuit switch which should be better inversely operating field-effect transistor. Converter is most useful when low-resistance short circuits across its output should be considered. EFFECT: improved operating reliability. 6 cl, 8 dwg
