POWER SUPPLY DEVICE FOR ELECTRONIC SCHEMES Russian patent published in 2018 - IPC H02M3/07 

FIELD: electrical engineering.

SUBSTANCE: invention relates to power supply devices of electronic circuits. According to the invention, the electronic circuit is powered by two independent capacitive storage devices, which in turn are connected to the voltage source to accumulate the charge, and after the accumulation of charge – to the power circuit of the electronic circuit for the discharge. In this case, switching of capacitive storage devices between the voltage source and the supplied electronic circuit is made by a control circuit in accordance with the principle: one drive is in antiphase with respect to the other. To exclude a pause in supplying voltage to the circuit of the electronic circuit, when switching from a discharged capacitive storage device to a charged electronic circuit for a time, both capacitive storage devices are connected. At the same time to exclude the discharge of capacitive storage devices on each other drives are unconnected from each other by means of diodes.

EFFECT: technical result of the invention is the decoupling of capacitive storage devices among themselves, the lack of the need to select the capacities of storage devices and the absence of the need to monitor the level of charge of capacitive storage devices when they are charged.
