Abstract

A chopper-type of d.c.-to-d.c. conversion to control fluctuations of the supply voltage from 90 to 250 V include between the pos. and nev. terminals of a d.c. source a primary winding (11) a damping network with a resistor (21) and a diode (22) in parallel and a measuring resistor (8). The chopper transistor (7) is protected by a capacitor (31) diode (33) and resistor (32). The secondary winding (51) is joined to the transducer base via an interrupter (51) and an inductive dipole (13). The interrupter is closed during the conductive times so that the feedback voltage is applied to the transistor base without being reduced by the voltage of the voltage generator (41). When the interrupter is open the voltage supplied by the generator is applied between emitter and base of the transistor without being short-circuited by the secondary winding. This removes the high saturation of the chopper transistor in the conventional circuit and the transistor operates under better conditions.
