Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To eliminate the current unbalance among switching elements connected in parallel with each other with high accuracy. SOLUTION: Current sensing voltages VCS1-VCSn which are the detecting values of main currents of (n) (>=2) sets of IGBTs connected in parallel with each other are used for arithmetic processing after the voltages VCS1-VCSn are converted into digital forms. After the voltages VCS1-VCSn are converted into collector currents I1-In by using constants G1-Gn and VOFFSFT1-VOFFSFTn (step 103), the deviation ΔI1-ΔIn from the average value IAVG of the collector currents I1-In are calculated (steps 104 and 105). Drive control voltages VD1-VDn are updated by the variation ΔVD1-ΔDn obtained by multiplying the deviation ΔI1-ΔIn by a coefficient Kij (steps 106 and 107). The drive control voltages VD1-VDn are supplied to the IGBTs as gate voltages VGE after the voltages VD1-VDn are converted into analogue forms.  The constants G1-Gn and VOFFSFT1- VOFFSETn are individually prepared at every switching element (IGBT).
