Abstract
Methods and systems for energy recycling are described. One example energy recycler includes an input to receive an input voltage, an output to couple to an inductor, a resonant tank, a switching circuit coupled between the input, the output, and the resonant tank, and a controller coupled to the switching circuit. The controller is configured to control the switching circuit to selectively couple the input voltage to the output, and couple an induced voltage from the inductor to the resonant tank when the input voltage is decoupled from the inductor.
Claims15
An energy recycler comprising:
- an input configured to receive an input voltage and couple to a first battery and a second battery;
- an output configured to couple to an inductor;
- a resonant tank;
- a switching circuit coupled between said input, said output, and said resonant tank;
- an analog controller coupled to said switching circuit, said controller configured to:
- control said switching circuit to selectively couple the input voltage to said output;
- couple an induced voltage from the inductor to said resonant tank when the input voltage is decoupled from the inductor;
- selectively couple the first battery to said input to provide the input voltage during a first period of time and selectively couples the second battery to said input to provide the input voltage during a second period of time;
- and
- selectively couple energy stored in the resonant tank to a load, the load comprising the second battery during the first period of time and the first battery during the second period of time.
