The self-made independent element 50W hi-fi power amplifier circuit

Published:2011/8/23 22:13:00 Author:Borg | Keyword: independent element, hi-fi, power amplifier

The power amplifier stage of the amplifier circuit consists of the compensatory tube emitter follower, the backward feedback of the big circuit makes the drive compensatory tube signal in the linear range. The circuit makes sure the 2 tubes conduct in different time in the structure, so the power supply won't be short. Ideal transistors can conduct or block quickly, however, triodes switch speed is limited, not to say the large power tube. When the changing signal which is put in the tube is reversed, the 2 tubes may be conducting at the same time.   (View)

The circuit modulates 555 multi-resonance by using the capacitance sensor that measures movement and pressure, the frequency is tested out by the NE560B PLL integrated circuit, and it generates the DC output voltage. The sensor zero frequency can be tested out by the 12-pin of NE560B. The VCO (voltage control oscillator) frequency of the PLL circuit should be tested out from the 2N3393 emitter which connects with 5-pin.   (View)

Three electromotors sequence-start reversed order stop circuit

Published:2011/8/30 20:28:00 Author:Christina | Keyword: Three electromotors, sequence-start, reversed order, stop circuit

Some technological processes need the three electromotors, the sequence-start order is M1, M2, M3, the reversed order is M3, M2, M1. In this circuit, the normally open contact point of KM1 is connected into the control loop of KM2; the normally open contact point is connected into the control loop of KM3, if the KM1 will not close, the electromotor M1 is not the first start one, so the electromotor M2 can not start; also the M3, this is the sequence start. The reason of the reversed order stop is that the normally open auxiliary contact point of KM3 is connected with the two ends of the stop button STP2, the normally open auxiliary contact point of KM2 is connected with the two ends of the stop button STP1.   (View)
