A system includes a power optimized energy source, an energy storage optimized source, and a network that combines a first current from the power optimized energy source and a second current from the energy storage optimized source in order to power a load at least during a high power demand event, including by connecting the power optimized energy source and the energy storage optimized source using a parallel connection.

Battery systems with power optimized energy source and energy storage optimized source

A photovoltaic device includes at least one photovoltaic cell and a DC/DC converter electrically coupled to the at least one photovoltaic cell. The at least one photovoltaic cell and the DC/DC converter are integrated into a photovoltaic package.

A voltage regulator coupled to an unregulated DC input voltage source by an input terminal, and to a load by an output terminal is disclosed. The voltage regulator converts an input voltage at the input terminal to an output voltage at the output terminal. The voltage regulator includes one or more slaves, and each slave includes a switching circuit which serves as a power switch for alternately coupling and decoupling the input terminal to an intermediate node. The voltage regulator also includes a filter coupled to the slaves, the filter including one or more inductor banks each of which having a predetermined number of inductors.

An M phase coupled inductor includes a magnetic core including a first end magnetic element, a second end magnetic element, and M legs disposed between and connecting the first and second end magnetic elements. M is an integer greater than one. The coupled inductor further includes M windings, where each winding has a substantially rectangular cross section. Each one of the M windings is at least partially wound about a respective leg.

A voltage regulator is operated by, during a finite period of a voltage regular start mode having a plurality of current pulses, monotonically increasing the maximum current of the current pulses and a target voltage.

A method of providing power includes providing no power to an output device if the output device cannot or should not use power. If the output device can use power, power is provided to the output device from an input source. If power available at the input source would not overload the output device, power is provided to the output device from the input source according to a maximum power point tracking algorithm. If power available at the input source would overload the output device, power is provided to the output device from the input source according to a target power.

Method of battery charging and power control in conjunction with maximum power point tracking

A multi-phase, coupled-inductor, DC-DC voltage converter operates in discontinuous conduction mode (DCM) when the system is operated at low output power demand. An embodiment of the converter switches to operating in continuous conduction mode (CCM) when the system is operated at high output power demand. Operation in single-drive and rotating phase DCM operation at low power are described. An alternative embodiment operates in a multiple-drive, rotating-phase, discontinuous conduction mode during at least one condition of output power demand.

Method and apparatus for multi-phase DC-DC converters using coupled inductors in discontinuous conduction mode

A voltage regulator coupled to an unregulated DC input voltage source by an input terminal, and to a load by an output terminal is disclosed. The voltage regulator converts an input voltage at the input terminal to an output voltage at the output terminal. The voltage regulator includes one or more slaves, and each slave includes a switching circuit. During each switching period of the switching circuit, the current for the slave is checked; namely, after the beginning of a low-side conduction period, and before the beginning of a high-side conduction period.
