FIELD: electrical engineering.SUBSTANCE: in the power supply system, introduction of a second choke coil, a capacitor and a second key element into the voltage stabiliser enables usage of the latter, during the second key element switching, as an up-converter of accumulator battery voltage which ensures onboard consumers feeding with accumulator battery electric energy, there being no energy in the solar battery; introduction of a third key element into the voltage stabiliser enables usage of the latter, during the third key element switching, as an up-/down-converter of solar battery voltage which ensures onboard consumers feeding with solar battery electric energy, battery voltage having dropped below that of the onboard consumers; introduction of a fourth key element and a second diode into the voltage stabiliser switches the choke discharge circuit from the first to the second diode when the second key element is disconnected which disconnects the choke discharge circuit from the accumulator battery.EFFECT: equipment quantity reduction, extension of the range of allowable reduction of the solar battery voltage and possibility to disconnect the solar battery.1 dwg |
