ABSTRACT:
A method and a system for measuring a quantity, such as current, of a power converter apparatus including parallel-connected power converter units. A component quantity, of each power converter unit is measured, transmitted digitally in serial communication format to a control unit (CU), and summed to produce a summed quantity. The component quantity data are transmitted to the control unit with the least significant bit (LSB) first. The summing is started as soon as the LSBs of the component quantities have been received. The LSB of the sum is transmitted further as soon as the LSBs of the component quantities have been summed. After this, the rest of the bits are summed in the order of arrival, with the most significant bit (MSB) last. The respective summing data are transmitted further in the order of arrival as soon as the corresponding bits of the component quantities have been summed.
