Filed: 1999-10-20
Abstract: PROBLEM TO BE SOLVED: To improve the heat resistant stress characteristics of a power semiconductor module. SOLUTION: In a power semiconductor module, a plurality of power semiconductor elements 1a and 1b are jointed to one insulating substrate 4, and the insulating substrate 4 is jointed/laminated to a base plate 7. A groove 11 for dividing the insulating substrate 4 into plural substrates is formed in the insulating substrate 4. At least one power semiconductor element (1a or 1b) is arranged in the insulating substrate 4, divided by the groove 11.  Even if the thermal stress of a junction part with the enlargement of the junction area of the insulating substrate and the base plate becomes large with the junction of the plural power semiconductor elements to one insulating substrate for reducing assembly man-hours and the trouble of parts management, the insulating substrate is cracked and the insulating substrate is separated at the part of the groove or a through hole string before a crack occurs in the junction part or a jointed member is peeled through thermal stress. Thus, a junction area per insulating substrate becomes small and thermal stress becomes small. Thus, the occurrence of the crack and peeling can be prevented, the heat radiation characteristic of the power semiconductor element is maintained, and heat destruction can be prevented.

Filed: 1990-11-02
Abstract: PURPOSE:To stably PWM control by fixing an electric angle to be accessed by a carrier signal to a predetermined value under a phase fixing control from when an inverter output frequency reaches a target value. CONSTITUTION:When an acceleration/deceleration is started, fixed phase is synchronized after the acceleration/deceleration is completed, and a PWM waveform is output at a fixed electric angle. the phase fixing control fixes,the electric angle for accessing by the carrier signal to a phase (theta2=theta0+ theta, thetam=theta0+(m-1)Xtheta,  theta=360 deg./(6Xn)) of theta1=theta0. Thus, the electric angle to be accessed by the carrier signal in each cycle of an arbitrary inverter output frequency becomes constant. In a synchronization switching control system, the specific phase of the PWM output of the inverter is operated by the synchronous pulse output by a fixed phase system while taking the mode of the synchronous switching system in the specific phase by an aiding inverter, and the phases of the output voltages of both the operating and aiding inverters are synchronized with one another.
