摘要： A voltage converter connectable to a power source (PS) and a load (LD) provides a regulated output voltage (Vout) from a voltage (Vin) power source by switchable current paths including an inductive element (L). The voltage converter includes a plurality of switching elements for switching the current paths of the voltage converter as a forward-phase current path when the input voltage corresponds to the output voltage, as an up-phase current path when the input voltage is lower than the output voltage, and as a down-phase current path when the input voltage is higher than the output voltage. A central controller controls a switching state of the plurality of switching elements, a current sensing unit including a comparator for sensing a current flowing through at least one of the switching elements, and a plurality of processing units for processing the current sensing.

摘要： The present invention relates to a DC to DC converter system (100), which comprises converter means (110) and control means (120). The switching sequence of the first, second and third switching means (S1, S2, S3) is controlled by the control means (120) in such a manner that, during the on-time of the second switching device (S2), the first current (II) that flows through the inductive storage element (L) of the converter means (110) can be indirectly measured through the first voltage (VC1) across the capacitive storage element (C1), which is being charged with a second current (12) proportional to the input voltage (Vin) of the converter means (110) and provided by the current source (CS). Thus, the on-time of the second switching means (S2) varies inversely proportional to the input voltage (Vin).

摘要： A multi-output DC to DC converter can have complex control requirements in CCM mode because of the differing load requirements of the outputs. A multi-output DC to DC converter having a single coil or inductor and a freewheel switch is described. A controller measures the duration of the freewheel phase. The controller increases the current supplied to the DC to DC converter in the following duty-cycle if the duration is less than a first value, and decreases the current supplied to the inductor in the following duty-cycle if the duration is greater than a second value.

摘要： A photovoltaic assembly is disclosed which comprises a string formed from a plurality of series-connected photovoltaic generators, and a hierarchical structure of power-exchange units, which each exchange power between neighboring photovoltaic generators or groups of photovoltaic generators. The photovoltaic generators may be individual solar cells or a plurality of series-connected solar cells arranged as a segment. To compensate for differences in output between segments for instance due to partial shading, power-exchange units, such as DC-DC converters, are arranged across neighboring segments, such that each power-exchange unit effectively sources or sinks current between neighboring segments to current-match the string. To avoid unnecessary “rippling” of power matching along many power-exchange units and the associated power loss due to many power-exchange units operating at less than 100% efficiency, the power-exchange units are arranged in a hierarchical structure. A method of operating such a photovoltaic assembly is also disclosed.
