POWER SUPPLY SOURCE OF CONSTANT POWER Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: power supply source has inductive-capacitive converter, choke composed of two equal parts 1 connected in series siding and located on different legs of magnetic core and capacitor 2 having equal reactances over frequency of supply network, rectifier diodes 4. Each winding of choke is additionally provided with magnetization winding 3 connected in opposition to part arranged together with it on same leg of magnetic core and linked with one lead to anode (cathode) of proper diode 4 and with other lead - to load 5. Free leads of cathodes (anodes) of diodes 4 are connected to corresponding common free leads are linked to input leads meant for connection of proper phases of supply network. EFFECT: improved efficiency of power supply of loads demanding constancy of fed power. 3 dwg
