Power Supplies

Acree offers Pulsed Power Supplies (PPS) for powering pulsed coating systems and other applications. Acree’s PPS supplies are designed to deliver 100’s of volts to kilovolts and 100’s of amps to kiloamps of electrical power to plasma sources. We design and build our PPS supplies to meet our customer’s specifications. If it’s kilojoules of energy, high peak current or rep-rate demands, Acree can custom build a PPS to match your needs. Our pulsed power supplies are used in pulsed PVD coating systems, aerospace research and as trigger sources for DC cathodic arc systems. They are simple, robust and powerful. The typical PPS supply for a pulsed cathodic arc deposition system runs at 700 volts and delivers 1,000 amps with a pulse width of 500 µs and a repetition rate of 100 Hz. The voltage is adjustable and our PPS supply can be preset to stop after a number of pulses, allowing precise control of film thickness. Or it can be externally triggered by the customer’s system.
