Abstract: A charge control system of one or more batteries B is electrically connected with one or more solar panels S, so configured to obtain the maximum transfer of power from such one or more solar photovoltaic panels S and for controlling the charge of the one or more batteries B. The control system includes: at least one tracking device of the point of maximum power or MPPT 2 adapted to adjust one of its input impedance seen from panels S for a power adaptation with panel S; at least one protection circuit of the system 3 adapted to avoid damages to the charge control system caused by inverted currents, coming from such battery B and from one or more electric equipment 8 connected with it.

Abstract: A level shifting circuit provides a reference bias voltage to permit signal transfer between two circuits with different common voltage reference levels. The bias voltage is less than a common voltage reference level for either of the two connected circuits. By providing the bias voltage, the range of variation for the common voltage reference levels between the two circuits is increased when the reference voltages float with respect to each other. The level shifting circuits permit signals to be transferred from a low voltage to a high voltage circuit with increased reliability and noise immunity, and vice versa. The level shifting circuit is particularly useful for driving a half bridge switch configuration, and transmitting a floating current sense signal.

Abstract: A modular power drive system includes a control module and a power module that are coupled together with standard connectors. The control module includes several interfaces for communication and a high speed processor to provide intelligent power control. The control module includes gate drivers, a power supply and current sense feedback circuitry for providing a closed loop power control. The power module includes power switches, power diodes and current sense resistors for driving a commanded output power level. The modular construction of the power driver permits separation of noise sources and noise sensitive components, and the construction of the control module board acts as a mechanical cover and electrical noise shield for the power module.
