Abstract
A circuit providing a constant voltage power source for a remotely controlled electrically operated device. The circuit includes a main battery operatively connected with a motor. The secondary battery is connected in parallel with the main battery and operatively connected with a wireless receiver. The negative terminals of both batteries are connected with the receiver through a double-pole single-throw switch and a series connected diode and inductor are interposed between the positive terminals of the batteries so that the secondary battery is charged by the potential of the main battery each time the switch is closed and current flow from the secondary battery to the main battery is prevented by the reverse bias of the diode.
Claims5
A circuit providing a constant voltage power source for a remotely controlled electrically operated device, comprising:
- a main battery;
- a primary motor operatively connected with said main battery;
- a secondary battery connected in parallel with said main battery,
- said secondary battery being a sealed at least partially rechargeable battery having a current capability substantially smaller than the main battery;
- a wireless receiver connected with the positive terminals of said batteries;
- a double-pole single-throw switch having its respective poles interposed between the respective negative terminals of said batteries and said receiver for simultaneously energizing the receiver and applying charging potential, when closed, from the main battery to the secondary battery;
- and,
- discharge preventing means interposed between the positive terminals of said batteries for preventing discharge of said secondary battery to said main battery.
