  • Publication number: 20230299688
    Abstract: Provided are switching elements 4, gate driver ICs 5 controlling the switching elements, and substrate 1 carrying the gate driver ICs. Substrate 1 includes base 2 and conductive portion 3 with obverse and reverse surface conductive layers 31, 32. Obverse surface conductive layer 31 includes first connection portion 311 connected to control signal output terminal 51 of gate driver IC 5, second connection portion 312 connected to gate electrode 411 of switching element 4, and first wiring portion 313 interposed between first and second connection portions 311, 312. At least one obverse surface-side first electronic component 61 is provided on obverse surface of substrate 1, forming a circuit portion connecting first and second connection portions 311, 312 together with first wiring portion 313. No conductive member penetrating through base 2 in the thickness direction is connected to first wiring portion 313. These configurations increase the speed of drive control.

  • Patent number: 10502115
    Abstract: In order to supply a reducing agent to an NOx catalyst in an appropriate manner when the temperature of the NOx catalyst is high, in cases where the temperature of the NOx catalyst is equal to or higher than a predetermined temperature at which ammonia is oxidized, and in cases where an NOx reduction rate in the NOx catalyst is smaller than a predetermined lower limit reduction rate, when the addition of the additive agent is carried out at least twice by changing an equivalent ratio with respect to an amount of NOx flowing into the NOx catalyst, the equivalent ratio in equivalent ratio control is made larger in the case where an amount of change of an amount of reduction of NOx accompanying a change of the equivalent ratio is larger than an amount of change of an amount of oxidation of ammonia accompanying the change of the equivalent ratio, than in the case where it is smaller than that.
