Haefely PIM 100 Combination Wave Impulse Module

Haefely PIM 100 Combination Wave Impulse Module
PIM 100 Hybrid module, uses a highly reliable semiconductor switch (unlimited lifetime, maintenance-free) to achieve a clean oscillation free impulse, which can be synchronized to within ±1° of programmed phase angle.

A discharge switch has two functions. It must have a DC voltage withstand capability that allows the energy storage capacitor to be charged and then discharged through wave shaping networks. Ideally, the switch should have infinite resistance during the charge cycle and zero resistance during discharge. Triggering of the switch can be very accurately controlled from the gate terminal.
