Abstract
An apparatus including an energy storage device and a power processing unit that is coupled to the energy storage device. The energy storage device is configured to deliver electrical energy to a load. The energy storage device also is configured to receive electrical energy from a source. The power processing unit is configured to control a fluctuation in voltage across the energy storage device while electrical energy is received by the energy storage device, or while electrical energy is delivered from the energy storage device to the load.
Claims26
An apparatus comprising:
- a. an energy storage device configured to deliver electrical energy to a load, and configured to receive electrical energy from a source;
- and
- b. a power processing unit coupled to the energy storage device;
- c. wherein the power processing unit is configured to control a fluctuation in voltage across the energy storage device while electrical energy is received by the energy storage device, or while electrical energy is delivered from the energy storage device to the load.
A power processing unit configured to control a fluctuation in voltage across an energy storage device as electrical energy is received by the energy storage device, or as electrical energy is delivered from the energy storage device to a load, the power processing unit comprising:
- a. a switching module including:
- i. an inductor, and
- ii. a plurality of switches coupled to the inductor;
- and
- b. a control module including a pulse generator that is coupled to the plurality of switches.
A method for controlling a fluctuation in voltage across an energy storage device as electrical energy is received by the energy storage device, or as electrical energy is delivered from the energy storage device to a load, the method comprising:
- a. providing an energy storage device;
- b. providing a power processing unit coupled to the energy storage device;
- and
- c. using the power processing unit to control the fluctuation in voltage across the energy storage device as electrical energy is received by the energy storage device, or as electrical energy is delivered from the energy storage device to a load.
