摘要： A surge voltage target setting unit obtains a main circuit power supply voltage of a semiconductor power conversion device based on an inter-terminal voltage of a semiconductor switching element detected by a voltage detection unit, and sets a control target of a surge voltage in accordance with the obtained main circuit power supply voltage. An active gate control unit, when the semiconductor switching element is turned off, sets a quantity of voltage modification so as to modify a gate voltage in a direction raising the gate voltage, that is, in a direction lowering a turn-off speed, based on feedback of the inter-terminal voltage, when the inter-terminal voltage exceeds the control target.

摘要： A pressure member contacts with a heating member 23 to form a nip part N where a recording material P is heated and pinched-conveyed, and includes a first elastic layer 24a and a second elastic layer 24b having higher thermal conductivity than that of the first elastic layer. An elastic layer is formed in combination of the first elastic layer and the second elastic layer so that the thickness of the second elastic layer at the end portion is thicker than the thickness of the second elastic layer at the center portion in a longitudinal direction perpendicular to a recording material conveyance direction. Accordingly, in the pressure member contacting with the heating member to form the nip part, it is possible to reduce a difference between a center nip width and an end-portion nip width of the nip part.

摘要： If the magnitude of a voltage command vector to a motor driver is smaller than a preset value in a control period, in each of a predetermined number of subsequent control periods (a compensation period), a pulse voltage vector is added to the voltage command vector so as to make substantially zero the average value of the added pulse voltage vectors during the compensation periods, and the compensated voltage command vector is used for the subsequent calculation. Also, two direction data for each phase winding are stored at the center of each of the two dead times following the edges of a voltage command pulse in each control period. An estimated phase voltage is calculated from the last voltage command pulse width, a phase voltage fluctuation during the two dead time of each control period and the stored direction data. The rotor position angle is precisely calculated from the estimated phase voltage.
