Method for transmitting analog and digital information while transmitting energy
Abstract:
The invention relates to a method for transmitting analog and digital information while transmitting energy between a power transmitter (10) and a power receiver (12) which is galvanically isolated from the power transmitter, having the following steps: a) providing the analog (22a) and digital (24a) information to be transmitted; b) defining the number nAD of possible values ADi, i=1 to nAD which are possible when digitizing the analog information and defining the value range of the values ADi; c) assigning a digital value Dx (in binary notation) to the digital information; d) defining a minimum number of events nmin to be transmitted; e) determining a maximum number of events nmax to be transmitted; f) defining a first set of values nlow defined by: nlow (ADi)=nmin+f1(ADi), i=1 to nAD; g) defining a second set of values nlow defined by: nhigh(ADi)=nmax−f2(ADi), i=1 to nAD; h) digitizing the analog information in order to obtain a digital analog value ADx; i) determining a number of events nlow(ADx)=nmin+f1(ADx) for the respective digital value Dx bit to be transmitted if the current digital value Dx bit to be transmitted is a 0; and defining a number of events nhigh(ADx)=nmax−f2(ADx) for the respective digital value Dx bit to be transmitted if the current digital value Dx bit to be transmitted is a 1 or vice versa; and j) transmitting a signal which correlates at least to the number of events determined in step i). The invention further relates to a corresponding device for carrying out the method.
