It has the welding currentfeedbackcircuit and the welding voltage feedback circuit.
具有焊接电流反馈控制电路及焊接电压反馈控制电路。
2
Because the circuit needs current overload protect, a double loop strategy , with current feedback of filter inductance as inner loop and output voltage as outer loop, is studied.
根据需要电路电流过流保护的特点，重点介绍了滤波电感电流反馈做内环，输出电压做外环的双环控制策略。
3
Combined with wide band currentfeedback amplifier, FET input circuit and programmable circuit, variable gain amplification circuit with high speed and high input impedance is designed.
