摘要： An electric power conversion system includes: a primary electric power conversion circuit including a primary coil connected to a connection point between a plurality of transistors; a secondary electric power conversion circuit configured similarly to the primary electric power conversion circuit and including a secondary coil corresponding to the primary coil; and a control circuit controlling transfer of electric power between the primary and secondary electric power conversion circuits. The control circuit executes feedforward control for setting one of an on/off ratio of a terminal voltage signal of the primary coil and an on/off ratio of a terminal voltage signal of the secondary coil, in response to at least one of fluctuations in voltage ratio between both waveforms and fluctuations in phase symmetry between both waveforms, when the terminal voltage waveform of the primary coil and the terminal voltage waveform of the secondary coil are different from each other.

摘要： An exhaust silencing device connected to an exhaust system of an engine is provided in which two outlet pipes that have at an upstream end thereof an opening portion opening within the silencer main body and that discharge exhaust gas within the silencer main body to an outside thereof are disposed within the silencer main body along a bottom thereof so that the distances thereof from the lowest part of the bottom are substantially equal, and the opening portion of one outlet pipe is directed further toward the bottom of the silencer main body than is the opening portion of the other outlet pipe. Such exhaust silencing device efficiently discharges to the outside the condensed water building up within the silencer main body so as not to impair an effect in reducing exhaust resistance by providing two outlet pipes that guide the exhaust gas to the outside.
