    Please help in the MOSFET driver

    Hi guys! well i was using the following schematic for my H-bridge in order to drive a DC motor. This circuit is fine for a small motor. Now i want to use a relatively more powerful motor whose current can get increased from 3A. The TC4424 can only support a peak current of 3A. So using this...

    Shutter Mechanism

    Hi guys! well! suppose that i have a tunnel that is having a slope i.e. When a tennis ball is inserted from its top end, it automatically floats to the bottom end and comes out of the tunnel due to slope. Now if i insert, lets say 8 balls in that tunnel one behind the other, so the balls will...

    Help me in finding the POWER MOSFET Driver

    Hi guys! well! im using a 3A dual High Speed Power Mosfet driver named as TC4424 in a circuit of H-bridge to control a DC motor. Now as i have written it can only support a peak current of 3A. I want to run a motor whose peak current is greater than 3 A but less than 5A. What should be the...

    Problem in an H-Bridge

    Hi Guys! well! i have made the following H-bridge which is made up of BJTs. Im providing it with the PWM through my PIC. The problem that im facing here is this that my DC motor is just not running with this circuit. The PIC seems to be working fine but there is no motion in the motor. When i...

    Does Infra red get reflected from white surface?

    Hi guys! well me, in a robot thinking of using an infra red LED and a detector to track a line made up of a white reflector tape often used in cars. someone just told me that the infra red gets absorbed in a white surface and cannot get reflected. Is it true? if yes then what idea should i...

    amplifiers used in Radar Immunization ??

    HI Guys! well! i have read somewhere that the waves generated by a primary radar adversley affect the electronic components of the vehicles that travel in the vicinty of the airport. To immunize these effects, TWT amplifiers and Class C amplifiers are used. I want to ask you two questions...

    Capacitor Voltage

    Hi Guys! well i want to ask you about the voltage ratings of an electrolytic capacitpr. I want to know that why these capacitors are categorized by their voltages. Like there is a capacitor of 100uF of 12V and there is a capacitor of 100uF of 50V. WHat is the difference between the two...

    help me in finding this output from a single op-AMP

    Hi Guys! well ! i want to use a single op-AMP with a +-15V DC supply. Remember that no other external DC supply is to be used except that. and i want to get the following output. Vo=Vi + 5 now what i have in my mind is this. That i make a voltage follower that is a unity gain amplifier. and...

    Op-Amp with a load resistor..Plz help

    Hi Guys! well! im just a bit confused here. i want to ask you a question: just have a look at the fig below which i have posted. You can see a load resistor "RL". my question is that whenever i studied this inverting configuration of opAmp, there is no load resistor given for it. So, now...

    please answer these two questions:

    hi Guys! well! i want to ask you people two very important questions: 1) Why electrical energy is prefered over other forms of energies? 2) What are electrical machines. If you think that electrical machines convert electrical energy into another form of energy or vice versa, please keep...

    working of negative feedback

    Hi Guys! welll! taking an example of an OP-AMP, i want to ask you that it it said that a negative feedback is used to 1)stabilize the voltage gain even if there occurs some change in the input signal voltage. 2) to decrease the gain of the OP-AMP so that it cannot go into the saturation...

    Teleconferencing please help

    Hi Guys! well! i have seen this circuit over some site. this circuit will enable one person to talk to two different persons on different telephones simultaneously. I can explain it like this suppose that "A" calls "B", B recieves the call and puts it on hold and then dials C on another...
