Power analysis software enables insight into system behaviours

The rapidly growing power-conversion market now extends into applications requiring complex dynamic power analysis during time periods as short as a single device-switching cycle.

Conventional power-analyser instruments cannot perform dynamic power analysis and are limited to long power-period (e.g. 5Hz to 500Hz) analysis.

The new software package now enables more thorough power-conversation system evaluations and provides deep insight into complex dynamic system behaviours in applications including DC-DC power supplies, hybrid/electric vehicles, solar PV and grid-tied inverters, welding equipment, uninterruptible power supplies and HVAC systems.

Capabilities include:

• Numeric measurement table to display mean value “static” power behaviours
• Per-cycle Waveforms of “dynamic” power enables the correlation of complex power conversion system behaviors to other control or power system waveforms to debug drive system problems
• Zoom+Gate mode for time-correlated, instantaneous understanding of dynamic power behaviors, and complete correlation to control system and other behaviors
• Harmonic order calculations with tabular and spectral displays and THD measurements (available in optional Harmonics software package)
• Support for two-wattmeter method to make accurate 3-phase power measurements using just two voltage and two current signals.
