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. Br...

    We are looking for an experienced Electrical Engineer with knowledge of food/automation equipment to help validate heater circuit conversion for the Australian market. We make food forming equipment for the US market. Our specifications use 240VAC, 3-phase, 60 Hz to power to energize a hydraulic ram (motor) and to supply single phase voltage directly to the heaters in our forming dies. We also transform the 240VAC to 120VAC for control circuitry. The available power in Australia is 415VAC, 3-phase, 50 Hz. We have swapped motor components to accommodate, and our controls transformer can convert this power to 120VAC. However, we need to validate our design ideas for our forming die heaters is appropriate, a special challenge given current supply constraints are limiting c...

Here is what I need: Home the gripper open to a micro switch on power up and wait for run input. When the switch is pressed and not released, the motor should make the travel forward 800 steps and reverse 800 steps and stop while touching the home switch. The circuit should wait until I press again the "run" button to go forward to close the gripper and reverse again to home switch. I need it to travel a specific distance. I only need the .ino file for this.

Each connector has 6 wires: Gnd, two output for dc motor, ws2812 data, 5v, and a switch trigger. 4. Whenever a switch is pulled to ground, it will trigger the motor to pull for 1 second. 5. Whenever a motor is pulled, the ws2812 will start to light up. 6. After 20 seconds, the motor should reverse back. And the Ws2812 strip should light off. 7.
