Japanese Patent JPS5760644
Kind Code:
B2
Abstract:
A circuit for producing a stabilised direct output voltage from direct voltage source (1) whose output varies between upper and lower values, respectively higher and lower than the stabilised voltage, is designed for small and light construction. A push-pull circuit contg. two controlled electronic switches (2, 3) is driven by a control (9) which alternately supplies control pulses to the switches depending on the stabilised voltage input (U2). The switches are connected to the primary winding (10a, 10b) of a transformer (10) with a centre tap supplied from the voltage source. The secondary winding (10c) is connected to a rectifier circuit (14) whose output provides the stabilised voltage via a filter (19, 20). Commutator switches (11, 12, 13) are connected between the electronic switch junction (4) and the rectifier outputs (17, 18) and between the electronic switches and the primary winding.
