    • A power semiconductor device which makes a heat come hard to arise in a particular element and is able to control an increase of the amount of a power loss caused by a tail current, even in case that plural power semiconductor elements are connected in parallel is provided.A control part (CTa) performs a regional control instead of a general control that all of IGBT elements (PD1 to PD4) are made to operate identically with providing a PWM signal (S0) for all of the elements. In other words, when a certain pulse in a pulse row of the PWM signal (S0) is inputted, only a part of switches (SW1 and SW2) is turned on and only a part of the IGBT elements (PD1 and PD2) is made to operate, and when a next pulse is inputted, only the other part of switches (SW3 and SW4) is turned on and only the other part of IGBT elements (PD3 and PD4) is made to operate. Moreover, the operation described above is repeated.
    • 即使在并联连接多个功率半导体元件的情况下,也能够在特定的元件中产生热量的功率半导体器件,并且能够控制由尾部电流引起的功率损失量的增加 。 控制部分(CTa)执行区域控制,而不是通过为所有元件提供PWM信号(S 0)使得所有IGBT元件(PD 1至PD 4)都能够相同地进行通用控制。 换句话说,当PWM信号(S 0)的脉冲行中的某个脉冲被输入时,只有一部分开关(SW 1和SW 2)导通,并且仅一部分IGBT元件(PD 1和 PD 2)进行动作,当输入下一个脉冲时,只有开关(SW 3和SW 4)的其他部分被接通,并且只有IGBT元件(PD 3和PD 4)的另一部分被制成 操作。 而且,重复上述操作。
