CONSTANT VOLTAGE TRANSFORMER Russian patent published in 2005 - IPC

FIELD: transforming equipment engineering, can be used as transformer of constant voltage to constant voltage for secondary power systems.

SUBSTANCE: constant voltage transformer has key amplifier, electric power buses of which are connected to primary voltage buses, set-point generator connected by direct and inversed outputs accordingly to first and second inputs of key amplifier, output of which through serially connected throttle and capacitor is connected to middle point of capacity splitter, while in parallel to capacitor primary winding of transformer is connected, secondary winding of which through rectifier and capacity filter is connected to secondary voltage buses. Device additionally has first and second switch-on delay circuits, first and second diodes and second capacity splitter, connected between primary voltage buses and connected by middle point to output of key amplifier, first and second inputs of which through first and second switch-on delay circuits are connected to direct and inverse outputs of set-point generator, while first and second diodes are connected serially via back conductivity between primary voltage buses, and middle point of diodes connection is connected to point of connection of throttle and capacitor. Also provided is circuit of constant voltage transformer, operating for multi-channel load.

EFFECT: increased stability of loading characteristics due to implementation of additional recuperative diodes (diodes, through which process of returning of accumulated energy of power source back into power source occurs), and also better quality characteristics of secondary voltages by means of providing of quasi-resonance trajectory of alteration of output voltage of key amplifier, which is especially important during operation of device for multi-channel load.
