    • The invention relates to a bipolar high-volt power component, especially an IGBT, comprising a semiconductor body with two interspaced electrodes (K, A) arranged thereon and between which a drift line is configured in a first semiconductor area (1) having a first type of conductivity. Floating areas (7) having a second type of conductivity opposed to the first are arranged inside the semiconductor area (1), whereby said floating areas emit current carriers having a second type of conductivity into the semiconductor area (1) or receive them therefrom when the power component is switched on or off. Said floating areas are also connected to active areas (3, 2) of both electrodes (K, A) via an MOS transistor (8) with a channel that has a second type of conductivity or a bipolar transistor (9) with a base that corresponds to the first type of conductivity.
    • 本发明涉及一种双极性高电压功率元件,尤其是IGBT,设置有在其上的至少两个间隔开的电极(K,A),在它们之间形成在第一导电类型的半导体区域(1)的漂移路径的半导体本体。 此外,在半导体区域(1)的浮置区域(7)的第二的,相反的第一导电类型导电类型释放在电源接通或关断在半导体区域中的第二导电类型的功率器件的电荷载体(1),或由后者和经由相应的记录 MOS晶体管(8),其具有所述第二导电类型的沟道和双极晶体管(9)与所述第一导电类型的与所述两个电极(K,A)连接到所述有源区(3,2)将电源装置的连接的位置。
