Circuit arrangement for the power supply of an electrical load by means of a solar generator, in particular in a vehicle

Of discrete analog components without use of a microprocessor constructed circuit arrangement for supplying power to at least one electrical consumer (2), in particular a fan and / or an accumulator, by means of a solar generator (1), serving with one of the impedance matching between the solar generator and the consumer DC-DC converter (6) having a switch (T1) which is opened by means of a pulse width modulated control signal alternately and closed, which is acted upon by means of the output signal of a frequency generator (13) and a control signal of a regulator circuit assembly (20) pulse width modulator (14) is generated, wherein - a voltage measurement applied at the control circuit arrangement (20), which is a measure of the output voltage of the DC-DC converter (6), - the regulator circuit assembly (20) is designed so that the DC-DC converter output voltage is maximized by changing the applied Henden the pulse width modulator control signal, - a storage capacitor output depending on the output level of an operational amplifier (OP) is charging or discharging, - the control signal for the pulse width modulator (14) applied from the output of this storage capacitor (C7) voltage is formed thereby...
