高功率電路英語怎麼翻譯
1. 求高手翻譯（關於電氣專業英語的）
1 Power transformer USES a step-down transformer, the power grid voltage 220 V transform into need ac voltage. The ac voltage after rectification, can obtain electronic equipment need dc voltage.
2The design of the rectifier circuit big filter capacitance, so the power of the instantaneous large current power supply features, little noise and reaction speed, output ripple small.
3The filter circuit capactance filtering circuit, will the pulsation of the rectifier circuit output filter out most of the ingredients from a smooth direct current. This circuit adopts the 3300 u F / 100 V large capacitance C3, C4 output voltage more smooth, the power supply characteristics moment, suitable for take perceptual load
4By LM317 output voltage circuit is power, LM337 output negative supply. LM317 and LM337 are used internal thermal overload, contains over current protection, hot off and safety working area compensation of perfect protection circuit, makes the power supply can save the fuse, and so easy loss device.
Regulating circuit: to meet the needs of the different application situation and the voltage is set to can be adjusted. Output voltage calculation Uo = 1.25 by (1 + Rf/R), can choose precision resistor adjustable resistance, guarantee the precise output voltage can be adjusted.
5The protection circuit for linear power supply heat bigger, so the power to add enough radiator. Due to the high performance integrated circuits, which can simplify the circuit structure, highlight the power transformation of the key part of the problem. Through the commissioning and testing, circuit performance is good. The power not only can be used alone, also can be in other electronic equipment used in voltage or current stabilization source use
Keywords: dc power rectifier circuit voltage filter circuit circuit protection circuit

Circuit description
One, the transmitting circuit:
1, the system power: DC 3V
2: FORWARD, BACKWARD, press, RIGHT-WARD, LEFTWARD; respectively control forward and backward, turn right, turn left. Issued by the TX-2B remote control coding signal, the isolation circuit sends the oscillation frequency signal ( the isolation circuit is composed of a crystal, a triode, capacitors and other components ), amplified by the amplifying circuit and carrier, composed of a transmitting circuit and a transmitting antenna.
In two, receiving circuit:
1, the system power: DC 4.8V
By 2, the antenna and high-frequency oscillatory circuit receives consistent with the frequency control signal.
3, by IC RX-2B encoding, and control the corresponding components: decoding output amplification
When the decoding circuit of the received signals after decoding, if the forward signal, then the feet high level output, concts the triode transistor 945 945, by concting the drive system circuit transistor 772, 882 driving motors, it forward, other functions and so on, RX-2B in 6, 7, 10, 11 turn right, turn left foot, backward, forward and other functions of the output end.
3. 關於功率放大器的英文翻譯，專業高手進
這段文字，語法上問題較多，有的專業術語也查不到，但我盡力翻了，供樓主參考。
Power amplifier's input stage is used shoot follower as buffer input. 功率放大器的輸入級用發射跟隨器（shoot follower）作為緩沖器輸入。Second stage is used difference circuit as small signal voltage amplifier stage. 第二級採用差分電路作為小信號電壓放大器級。Set electricity stage as constant current source loading. 將電氣級設定為恆定的電流源負載。There is higher voltage gain and indissoluble work, small nonlinear distortion. 存在較高的電壓增益和不能分解的功，以及小的非線性失真。 Third stage's main voltage amplifier stage is used sharing shoot stage circuit. 第三級的主電壓放大器級採用共享的射發射級電路。Set electricity stage loading also is constant current source. It can make signal voltage amplifier to large enough. 同樣將電氣級負載設定為恆定的電流源。它可使信號電壓放大器足夠大。Between second and third stage also is used shoot follower to isolate. 在第二和第三級之間，也採用發射跟隨器來隔離。Fourth stage is output push stage. 第四級是輸出推挽級。Shoot follower is consisting of complementary middle-power double tubes, which are both installed on main radiator with bias control tube together. 發射跟隨器由補充的中功率雙管構成，它們都與偏置控制管一起安裝在主輻射器上。Such has good temperature compensation and make output stage work steadily. 這樣有良好的溫度補償作用，而且使輸出級穩定工作。Fifth is power output stage, is consisting of 150W Toshiba mutual-complementing double tubes (C5200/A1943), when working in Ⅰstate, there are higher efficiency and strong output power. 第五級是功率輸出級，它由150W的東芝互補雙管（C5200/A1943）構成，當在電流（I）狀態下工作時，具有較高的效率和強的輸出功率。
