Abstract: A parallel driving device that drives parallel-connected semiconductor elements includes a control unit and a gate driving circuit. The control unit detects a temperature difference between the semiconductor elements on the basis of detected values by temperature sensors that detect temperatures of the individual semiconductor elements. The control unit generates a control signal for changing the timing at which to turn on a first semiconductor element specified from the semiconductor elements on the basis of the temperature difference. The gate driving circuit generates a first driving signal for driving the semiconductor elements, and generates a second driving signal that is the first driving signal delayed on the basis of the control signal, and applies the second driving signal to the first semiconductor element.

Abstract: A transducer is provided, which includes an oscillator and a broadbanded matching circuit. In the oscillator, a peak frequency corresponding to a peak transmission sensitivity may separate from a center frequency in a given bandwidth, and a transmission sensitivity may increase as a frequency separates from the peak frequency with respect to the center frequency. The broadbanded matching circuit may be configured to perform an impedance matching so that the transmission sensitivity of the oscillator at the peak frequency becomes substantially equal to the transmission sensitivity of the oscillator at the center frequency.
