ABSTRACT:
A generator device for providing a controlled output current to a load, the device including a panel for generating electric current from light; a capacitor connected to the output of the panel; a source of stored energy; output terminals receiving power from the capacitor for connection to a load; a gear train connected to the source of stored energy so as to be driven thereby; a generator for supplying electric current to the output terminals and to the capacitor; output terminals for connection to a load; a source of stored mechanical energy; a generator for supplying electric current to a the output terminals and the capacitor; and a gear train connected to the source of the stored mechanical energy so as to drive the generator; a control circuit for controlling supply of electrical current to the output terminals from the panel, the capacitor and said generator, the control circuit including: a transistor switch arrangement for enabling current from the generator and the panel in excess of the load to charge the capacitor in addition to the output of the panel and for shorting the connection between the generator and the output terminals if the charge across the charged capacitor voltage exceeds a predetermined value. The release of mechanical energy is prevented and charge stored in the capacitor is enabled to supply power supplied to the load.
