- the measuring device 116 further comprises a diode D1 connected between the midpoint of resistors R2, R5 and the output terminal S.
- the switch arm 110 is in the first configuration: the high side switch Q6 is open, while the low side switch Q2 is closed.
- control system 114 begins at an instant t1 a switching from the first configuration to the second configuration, by controlling the opening of the initially closed switch, that is to say say, in this case, the low side switch Q2.
- the control system 114 monitors the LVCE switch voltage of the low side switch Q2 by monitoring the measurement voltage VM.
- control system 114 determines the dead time TM for the current switching from the monitored LVCE switch voltage.
- the control system 114 detects at an instant t2 that the switch voltage LVCE crosses a predefined threshold S.
- the use of the waveform advantageously makes it possible to limit rapid oscillations around the threshold, and therefore untimely detections.
- the control system 114 determines the dead time TM from the detection of the crossing.
- the dead time TM extends from the opening command (time t1) to the detection of the crossing (time t2).
- the dead time TM could be determined from the time interval t2 - 11 separating the opening command of the low side switch Q2 (instant t1) from the detection of the crossing (instant t2) , so that this dead time TM has an end after the detection of the crossing t2, in order to be able to be used for the switching in progress.
- the dead time TM could extend from the opening command (time t1) to the detection of the crossing (time t2) plus a predefined duration P1.
- the determination of the dead time TM would thus be carried out according to the following equation:
- the control system 114 records the dead time TM.
- control system 114 controls, at the end of the dead time TM, the closing of the switch initially open, that is to say, in this case, the high side switch Q6.
- the control system 114 commands as soon as the crossing is detected, the closing of the switch initially open, i.e. in this case the high side switch Q6.
- Step 218 could be performed before or during step 216.
- the switching arm 110 is indeed, during a step 220, in its second configuration: the high side switch Q6 is closed and the low side switch Q2 is open.
- the control system 114 begins a new switching at a time t3 by controlling the opening of the switch initially closed, that is to say, in the present case, the 'high side switch Q6.
- the control system 114 determines from the dead time TM of the previous switching, the dead time for the switching in progress.
- the dead time for the current switching is equal to the dead time TM for the previous switching.
- control system 114 controls the closing of the switch initially open, that is to say, in the present case, the 'low side switch Q2.
- the determined dead time could be greater than the dead time TM of the previous switching, for example equal to the dead time of the previous switching plus a predefined duration P2.
- the following equation could be used:
- the switching arm 110 is indeed, during a step 230, in its first configuration: the high side switch Q6 is closed and the low side switch Q2 is open.
- the process 200 can then be repeated by returning to step 202.
- the dead time of each of the successive switching operations is determined from the monitored switch voltage, while in the first embodiment of the invention, the dead times switchings from the second to the first configuration were each determined from the dead time of the previous switching (switching from the first to the second configuration).
- the method 400 comprises the steps 202 to 220 already described, relating to the switching from the first to the second configuration.
- the method 400 For the reverse switching (from the second to the first configuration), the method 400 comprises steps 204 ', 206', 208 'and 218' respectively identical to steps 204, 206, 208 and 218, if not is that the roles of the switches are reversed and that the threshold S2 is used instead of the threshold S1, which can give a dead time TM2 for the switching in progress different from the dead time TM1 for the previous switching.
- the midpoint M is connected to the electrical ground 104 to have the zero voltage applied and therefore have this zero voltage, while that in the second configuration, the midpoint M is connected to the direct voltage source 102 to have the direct voltage VHT applied and therefore present this direct voltage VHT.
- each of the predefined thresholds S, S1, S2 is between zero voltage and direct voltage VHT.
- the direct voltage VHT being positive, these thresholds are therefore positive.
- the threshold S and the threshold S1 are each between 85% and 95% of the direct voltage VHT, while the threshold S2 is for example between 5% and 15% of the direct voltage VHT.
- a switching system such as that described above makes it possible to determine the dead times only from the switch voltage and from predefined data (P1, P2 in the example described), independent of the '' operating state of the voltage converter and / or of the electrical machine.
- the dead times are determined by measuring the switch voltage, therefore with substantially similar reliability whatever the operating point of the electrical machine and with very simple material means: an adaptation of the control system and a measuring device which can be very simple like the one illustrated in FIG. 1.
- the dead time for the switching in progress could be determined from the monitored switch voltage, other than by detecting a threshold crossing.
- the dead time for the current switching could be determined from a slope of the monitored switch voltage.
- the measured switch voltage could be that of the high side switch, for example between the midpoint M and the DC voltage source 102.
- the invention is transposable to any electrical device using a switching arm, such as DC-DC voltage converters or on-board charger (standing for "On Board Charger"), and in particular when gentle switching is desired.
- a switching arm such as DC-DC voltage converters or on-board charger (standing for "On Board Charger"), and in particular when gentle switching is desired.
