可在涡轮发动机的高温环境中操作的电压调节器电路
摘要：
提供了一种适于在涡轮发动机的高温环境中操作的电压调节器电路(50)。该电压调节器可包括恒流电源(52)，所述恒流电源包括第一半导体开关(54)以及连接在第一半导体开关的栅极端子(G)和源极端子(S)之间的第一电阻器(56)。第二电阻器(58)连接到第一半导体开关(54)的栅极端子，并连接到电接地(64)。恒流电源联接成在第二电阻器(58)的两端产生参考电压。源极跟随器输出级(66)可包括第二半导体开关(68)以及连接在电接地和第二半导体开关的源极端子之间的第三电阻器(58)。所产生的参考电压被施加到第二半导体开关(58)的栅极端子。
摘要（英）：

A voltage regulator circuitry (50) adapted to operate in a high-temperature environment of a turbine engine is provided. The voltage regulator may include a constant current source (52) including a first semiconductor switch (54) and a first resistor (56) connected between a gate terminal (G) and a source terminal (S) of the first semiconductor switch. A second resistor (58) is connected to the gate terminal of the first semiconductor switch (54) and to an electrical ground (64). The constant current source is coupled to generate a voltage reference across the second resistor 58. A source follower output stage 66 may include a second semiconductor switch (68) and a third resistor (58) connected between the electrical ground and a source terminal of the second semiconductor switch. The generated voltage reference is applied to a gating terminal of the second semiconductor switch (58).
