FIELD: off line power systems for space vehicles. SUBSTANCE: system has power supplies each connected through respective regulator to output leads. Regulator supplied with power from its storage battery has control unit whose output is connected to control input of regulating element and input, to error sensor through adding unit. Control unit is made in the form of pulse-width modulator, its first adding amplifier has l inputs for connection to outputs of mentioned l error sensors. Output of second adding amplifier of regulator is coupled in addition to reference voltage source. Regulator incorporates series- connected current sensor inserted between regulating element and load. Its output is coupled with input of second adding amplifier. Regulator adding unit has battery setting current generating device whose input is connected to output of adding amplifier and output, to input of second adding amplifier. Connected to amplifier input are first leads of first, second, and third resistors; second lead of first resistor functions as input of battery setting current generating device. Second lead of second resistor is connected to terminal for connecting cycling-charge setting voltage supply. Second lead of third resistor is connected to terminal for connecting cycling-discharge setting voltage supply. Amplifier output is connected to anode of first diode whose cathode is connected to terminal for connecting charge-current setting voltage supply and to cathode of second diode whose anode is connected to discharge-current setting voltage supply. Output of mentioned amplifier functions as output for battery setting current generating device. EFFECT: enlarged functional capabilities; enhanced service life. 1 cl, 1 dwg |
