ENERGY ACCUMULATOR Russian patent published in 2024 - IPC H02J15/00 

FIELD: electronic equipment.

SUBSTANCE: energy accumulation device in a capacitor relates to the field of electronic engineering and, mainly, can be used in special equipment. For example, in control systems and devices (subscribers) of spacecrafts (SC) for elimination of single starting pulse of current of devices. In particular, where in the circuits of the primary power supply of the spacecraft in order to increase the noise immunity of the system, the starting current of the subscriber with an amplitude that is much greater than the amplitude of the current of the subscriber in its normal operating mode is inadmissible. Elimination of interference is of particular importance in special-purpose equipment, for example, in spacecraft equipment. Use of a capacitor instead of an inductor as an energy accumulator enables to reduce the WDC of the device. Electronic part can be made in the form of an IC chip similarly to the VLSI, the WDC of which, as compared to the WDC of the capacitor, at its discharge current of order of 10…20 A are negligible. Device power consumption is determined practically by value of stored energy W. In storage mode W there is no power consumption. End of the process of accumulation of energy W is fixed by a special signal. Value of voltage U_out of charge of series connection of two capacitors can be realized in the range of voltages 0<U_out=const<2⋅U_in. At the same time value of accumulated charge does not depend on change of input voltage U_{in_min}≤U_in≤U_{in_max}. For example, U_out=const=U_{in_max} at (U_{in_max}/U_{in_min})≤2. Value of direct current of the energy accumulator in the mode of accumulation W can be set equal to or less than the current consumption of the load in the standard mode of its operation. Energy storage time W is determined by capacitor charge leakage, their quality. Positive effect is the simplification of the device.

EFFECT: elimination of high-frequency interference when a subscriber is switched on in circuits of a primary DC power supply.
