The impedances of sources and loads in any system are very important to know and understand. Taking appropriate meaurements is critical in knowing the behavior complex impedances. Whether we are looking at interacions between an input filter and the modulator, or the impedance of a power bus and the total of serveral indepedent power supplies, conditions can exist that will actually cause unwanted (and ususally destructive) oscillations. Being able to view impedances versus frequency (Bode plot) and operate on them mathematically permits the engineer to have a deeper understanding. With this knowledge, one can implement appropriate design measures.
The Input/Output Impedance Measurement Set enables the engineer to perform input impedance and output impedance measurements on systems while the systems are under operational power. In this fashion, the true behavior of the system is revealed.
Venable's Input/Output Impedance Measurement Set allows engineers to characterize a power supply's ability to reject noise. Such tests are commonly refered to as Conducted Susceptibility or Power Supply Rejection Ratio.
Many, if not most, power supplies incorporate power factor correction. PFC circuits certainly affect the input impedance of power supplies that have power factor correction (not to mention that PFCs have their own stability issues).
Understanding three phase impedance is critical in large power systems. Venable Instruments is the only FRA provider that provides the instrumentation to measure three phase impedance.
Venable provides scalable energy storage and power systems test solutions for precise voltage, current, and frequency measurements, partnering with engineers to ensure battery and power systems around the world will meet stringent field performance demands.
