How Do You Make a Pulse in an RLC Circuit?
One of the fundamental roles of capacitors is charging and discharging energy predictably. Many electronics applications leverage capacitors to store energy and release it in a controlled pulse of current or voltage.
Specifying Capacitors for High-Energy Pulse Applications
Energy storage capacitor banks supply pulsed power in all manner of high-current applications, including shockless compression and fusion.
Generating High Voltage Pulses with Marx Generators
Pulsed energy drives a wide range of high-energy applications, from particle acceleration to fusion research and electromagnetic pulse (EMP) simulation. Marx generators play a critical role in generating those high-voltage pulses by amplifying lower voltage DC inputs.
How Pulse Forming Networks Shape High Energy Pulses
From high-power radar to advanced medical imaging, many cutting-edge technologies rely on precisely controlled high-energy pulses. However, generating a pulse that delivers consistent power without distortion isn’t as simple as discharging a capacitor. These systems rely on Pulse Forming Networks (PFNs) to shape and control high-energy pulses.
