Abstract

1298520 DC-DC converters TELEFONAKTIEBOLAGET L M ERICSSON 10 April 1970 [15 April 1969] 17280/70 Heading H2F [Also in Division H3] A transistor blocking oscillator having an output winding including a rectifier for connection to a capacitor to be charged thereby while the transistor is non-conducting, has a monostable flip-flop in the feedback path which is triggered when the voltage across the feedback winding falls below a given value during the non-conductive period of the transistor and renders the transistor conductive for a period too short to allow the transformer to saturate. A further monostable circuit may be provided to effect starting of oscillation.
