具体实施方式
本发明功率器件驱动装置的实施例一，如图1所示：
一种功率器件驱动装置，包括第一限流元件R1(电阻)、第二限流元件R2(电阻)、单向导通器件D1(二极管)、电容C1、稳压器件Z1(稳压二极管)、半导体开关OPT1，第一限流元件R1、单向导通器件D1、电容C1串联而成第一串联电路，第二限流元件R2、单向导通器件D1、电容C1串联而成第二串联电路，电容C1通过半导体开关OPT1、所需驱动的功率器件SCR1(单向晶闸管)的第二端(触发极)、功率器件SCR1的第三端(阴极)形成驱动回路，由功率器件SCR1的第一端(阳极)提供的第一电源通过第一限流元件R1对电容C1充电，第二电源(图1为中性线提供，在三相开关使用时，也可以由相对于功率器件SCR1的另一相线提供)通过第二限流元件R2对电容C1充电，稳压器件Z1与电容C1并联(也可以稳压器件Z1通过单向导通器件D1与电容C1并联)，功率器件SCR1的第一端、功率器件SCR1的第三端为功率器件SCR1主回路端。
工作原理：为方便理解，这里以用在单极机械开关灭弧的功率器件的驱动为 例，功率器件SCR1反向并联功率器件SCR2，在功率器件SCR1主回路端连接的机械开关K1常开状态下，由第一电源通过第一限流元件R1、单向导通器件D1对电容C1充电，在需要过零接通时，提供半导体开关OPT1控制信号，电容C1通过半导体开关OPT1驱动功率器件SCR1过零导通，机械开关K1闭合，关闭半导体开关OPT1导通控制信号，在功率器件SCR1主回路端常闭状态下(即机械开关K1闭合状态下)，由第二电源通过第二限流元件R2、单向导通器件D1对电容C1充电，满足功率器件SCR1所需的驱动能量；在机械开关分断时，提供半导体开关OPT1导通控制信号，然后机械开关K1断开，功率器件SCR1导通，关闭半导体开关OPT1导通控制信号，完成机械开关K1的无电弧分断。注：为方便描述和理解，功率器件SCR2的控制相同就不再赘述。
本实施例，用于混合式开关的功率器件驱动，由于功率器件采用电容储能驱动方式，通过第一限流元件、第二限流元件的工作电流可设计在0.1毫安以下，当设定为0.1毫安，工作电压为220V，其功耗为0.022W。
本发明功率器件驱动装置的实施例二，如图2所示：
一种功率器件驱动装置，包括第一限流元件R1(电阻)、第二限流元件R2(电阻)、第一单向导通器件D1(二极管)、第二单向导通器件D2(二极管)、电容C1、稳压器件Z1(稳压二极管)、半导体开关(C)，还包括一用于控制单向晶闸管SCR1导通的光电耦合器OPT1，第一限流元件R1、第一单向导通器件D1、电容C1串联而成第一串联电路，第二限流元件R2、第二单向导通器件D2、电容C1串联而成第二串联电路，电容C1通过半导体开关(C)、所需驱动的功率器件SCR1(单向晶闸管)的第二端(触发极)、功率器件SCR1的第三端(阴极)形成驱动回路，由功率器件SCR1的第一端提供的第一电源通过第一限流元件R1对电容C1充电，第二电源(图2为中性线提供，在三相开关中使用时，也可以由相对于功率器件SCR1的另一相线提供)通过第二限流元件R2对电容C1充电，稳压器件Z1与电容C1并联(也可以稳压器件Z1通过第一单向导通器件D1与电容C1并联，增加另一稳压器件通过第二单向晶闸管D2与电容C1并联)，功率器件SCR1的第一端、功率器件SCR1的第三端为功率器件SCR1主回路端。功率器件SCR1为半控型器件，半导体开关(C)为一电压检测开关，电压检测开关包括电阻、半导体器件，半导体开关(C)与功率器件SCR1连接。
工作原理：为方便理解，这里以用在晶闸管开关的功率器件的驱动为例，功 率器件SCR1反向并联功率器件SCR2(为半控型器件，也可以为全控型器件)，在功率器件SCR1主回路端常开状态下，由第一电源通过第一限流元件R1、第一单向导通器件D1对电容C1充电，在需要过零接通时，提供光电耦合器OPT1控制信号，电容C1通过半导体开关(C)驱动功率器件SCR1过零导通，半导体开关(C)在检测到功率器件SCR1导通时截止，停止电容C1的放电，在功率器件SCR1主回路端常闭状态下(即功率器件SCR1导通状态下)，由第二电源通过第二限流元件R2、第二单向导通器件D2对电容C1充电，满足保持功率器件SCR1导通状态所需的驱动能量。注：为方便理解，由于功率器件SCR2的控制相同，不再赘述，光电耦合器OPT1不限于与晶体管Q1的集电极连接，光电耦合器OPT1也可以与晶体管Q1的基极连接。
当功率器件(单向晶闸管)长期导通需要持续提供驱动电流时，第一限流元件R1、第二限流元件R2将产生极大的功耗，为减少能耗，达到实用性，本实施例中，半导体开关(C)为一电压检测开关，通过第一限流元件R1、第二限流元件R2的平均工作电流可以远小于单向晶闸管所需的最小触发电流，通过第一限流元件R1、第二限流元件R2的平均工作电流可以为单向晶闸管所需的最小触发电流的几十分之一到千分之一，大大减低第一限流元件R1、第二限流元件R2的功耗；以上所述的单向晶闸管，其定义也包括任一等同器件。
如图3所示，为便于使用，可以对以上实施例的功率器件驱动装置封装在一绝缘材料内，增加相应引脚(对应图2的P1、P2、P3、P4、P5、P6)，以上实施例的功率器件驱动装置通过相应的引脚供外部连接。
在交流供电***中使用时，与本发明功率器件驱动装置连接的相对于功率器件的另一端电源也定义为中性线。
综上所述，本发明具有以下优点：
1.第一电源、第二电源由功率器件所在的工作电网非隔离供电，具有电路简单、成本低、可靠性高的优点。
2.采用两个反并联的全控型或半控型功率器件驱动时，可以采用相同的电源端供电，极方便在单相交流供电***中使用。
3.由于本发明的第一电源端可以由功率器件的第一端提供(并不限于)，第二电源端由中性线或相对于功率器件的另一相电提供，也很方便在三相三控的***中使用。
