Impulse GeneratorHow does it work?
An impulse generator produces short pulses of high-voltage.
‘n’ number of capacitors charged in parallel to a voltage ‘V’
Capacitors connected in series
System is triggered
Creates lightning!Gap Motor

Why is it important?
The impulse generator is used to run tests on equipment that can be put under high voltage stress. These tests help ensure protection to the equipment.

•Astable Operation- produces ‘square wave’-output continually changes between ‘low’ and ‘high’
•Monostable Operation-features RC circuit to set the output duration

Warning Siren
•Will feature a speaker with an integrated amplifier
•Should be capable of outputting in between 50-60dB

Software Testing• Move stepper motor to desired distance
• Wait for transformer output voltage to equal the desired Charging Voltage
• Yes• Signal is sent to triggering device• Stepper motor is returned to starting position
• Turn warning Siren and Light on
• Would you like to fire the trigger (Y/N)?
• No• Signal is not sent to triggering device• Stepper motor is returned to starting position
![Page 26: Team Members Heather Bartlett -Trigger Package Design (PCB, PIC) -Warning Lights Andrew Read -PC Software -Communications -System Design/Integration.](https://reader036.fdocuments.us/reader036/viewer/2022070413/5697bfc21a28abf838ca50f4/html5/thumbnails/26.jpg)
Controller TestingStepper Motor • 0 revolutions = 30 mm• 2 ½ revolutions = 77mm
Stepper Motor Driver• 200 steps/rev• PWM signal: one step/ period

Controller Testing Plan
• Run new tests for DAC Output from Controller to Voltage Controller
• Compare Voltage Controller Outputto desired value.
• Measure Sphere Gap spacing once installed in the HVL.
