    Design circuit You may use Multisim Construct a single phase, one-pulse SCR battery charger in Multisim. The same basic circuit as in section 1 above can be used, but replace the diode with a SCR and include a 340VP : ≈ 200VP (depending on your student number) step-down transformer between the ac supply and the SCR. Implement your circuit in Multisim using ‘virtual’/ideal components. Also add a 10-V firing/triggering pulse via a 10-Ω resistor to Gate and Cathode. You must have some form of delay in the pulse to fire at a certain angle Simulate typical output waveforms for the circuit (choose a firing angle α). Show voltage as well as current – and use a current probe to send the signal to the oscilloscope. Briefly discuss the waveforms to summarise t...

    Not processing more proposals. Follow the Sun is a 50' Solar catamaran. The boat has 2 motors, one in each hull. The motor forward speed is controlled by a 0 to 5v input signal. The motor backward speed is controlled by setting reverse (close contact) and 0 to 5v input signal. Turning is accomplished by reducing the motor speed on one side. Via throttle input or by autopilot command) The requirement is for a throttle circuit that will allow manual and autopilot control. Please contact me for further detail.

    I am designing two PCBs (a RF emitter and a RF receiver) and I would like to find someone to give me a hand with it. A summary of specs is presented below: - The emitter (Tx pcb) it is like a keyfob. It should incorporate an encoder (HT12D or similar) along with an RF emitter IC and a PCB printed antenna. This board will be powered with a coin cell (3V). There will be only 2 inputs coming into the encoder. - The receiver (Rx pcb) should incorporate a decoder (HT12E or similar) along with a RF receiver IC and a PCB printed antenna. This board will be powered with a single LiPo Battery (3.7V). There will be 4 outputs. This board should also incorporate a LiPo charging management circuit (TP4056 + DW01 + FS8205) and a DC-DC boost IC (MT3608 or similar) since one of the outputs requires 12...
