Transverter with three winding transformer - is suitable for electronic flash sets and has battery supply via astable multivibrator

摘要

Transverter especially for electronic flash equipment comprises a three-winding transformer whose secondary is connected to a capacitor via rectifier elements. The turns ratio is made variable in relation to the capacitor voltage, the connection between the secondary and the capacitor being made via an on-off switch designed more specif. as the working contact of an electromagnetic relay. Transverter supply is specif. made from a storage battery via an astable multivibrator and capacitively-coupled pnp switching transistors into the collector lead of each of which is connected the primary winding(s) of the triple-wound transformer.
