Abstract
A device for balancing power generators, including a plurality of converters each including an elementary conversion cell with a switch driven by a comparator that receives a ramp on one input thereof and, on another input, a voltage from a driving amplifier wherein the driving amplifiers receive on their negative input an image of the cell current and have their positive input connected to an adjustment loop including a common path CS_Bus, and wherein the CS_Bus path directly connects the positive inputs of the driving amplifiers to the outputs of transconductance amplifiers associated with the elementary conversion cells.
Claims12
A balancing device for power generators, having a plurality of converters, each including an elementary conversion cell equipped with a switch controlled by a comparator receiving, on one of its inputs, a control ramp and, on the other input, a voltage that comes from a control amplifier, wherein the control amplifiers receive on their negative input a measurement of the current from the cell, have their positive input connected to a regulation loop having a common CS_Bus path, and the CS_Bus path directly connects the positive inputs of the control amplifiers to the outputs of transconductance amplifiers, associated with the elementary conversion cells and, receiving on their negative input the output voltage of all the converters and on their positive input one reference voltage (Vref1, Vref2, Vref3, Vref4) per cell.
