Control circuitry and method for controlling a bi-directional switch system, a bi-directional switch, a switching matrix and a medical stimulator
Abstract:
A control circuitry (134) and a method for controlling a bi-directional switch (132) is provided. The bi-directional switch (132) having a control terminal (130) for receiving a control voltage (124) to control an on state and an off state of the bi-directional switch (132) and at least one semiconductor switch in a bi-directional main current path. The control circuitry (134) comprises an energy storage element (102), a coupling means (101) to couple the energy storage element (102) to a supply voltage to charge the energy storage element (102), and a control circuit (108) configured to receive power from the energy storage element (102) and pendent of the supply voltage when the emergency storage element (102) is not coupled to the supply voltage. The coupling means (101) is configured for only coupling the energy storage element (102) to the supply voltage when the bi-directional switch (132) is in the off state.
Abstract(Chinese):

提供了控制电路（134）和用于控制双向开关（132）的方法。 双向开关（132）具有用于接收控制电压（124）以控制双向开关（132）的导通状态和断开状态的控制端子（130）和双向开关（132）中的至少一个半导体开关 双向主电流路径。 控制电路（134）包括能量存储元件（102），将能量存储元件（102）耦合到电源电压以对能量存储元件（102）充电的耦合装置（101）和控制电路（108） ）配置成当所述紧急存储元件（102）未耦合到所述电源电压时，从所述能量存储元件（102）接收电力并且提供所述电源电压。 耦合装置（101）构造成仅当双向开关（132）处于关闭状态时才将能量存储元件（102）耦合到电源电压。
