PULSE MODULATOR Russian patent published in 2004 - IPC

FIELD: full storage discharge modulators. SUBSTANCE: pulse modulator has power supply 1 as well as series-interconnected charging choke 2, charging diode 3, and energy storage 4 connected to the latter; connected in parallel with energy storage 4 are electronic switch 5 and load 6 which function to discharge energy storage 4, Newly introduced in device are parallel-interconnected energy storages 4 and series-connected charging choke 7 and electronic switch 8. Voltage across load is increased due to step-by-step charge of energy storage 4 to voltage exceeding double value of voltage across power supply 1 due to recharging energy storage 4 through charging choke 7 and electronic switch 8 occurring during interval between two regular control pulses driving electronic switch 5 in conduction. EFFECT: provision for producing load voltage exceeding power supply value. 1 cl, 1 dwg
