Key Applications
Electrical Power Conversion Systems
Examples:
– AC/DC power supplies
– DC/AC inverters
– DC/DC converters
– Solar inverters
– Hybrid Electric Vehicles (HEV), Electric Vehicles (EV), and Plug-in Hybrid Electric Vehicles
(PHEV) inverters
Important power converter measurements:
– Power consumption
– Efficiency
– Harmonics and THD
– Response to dynamic conditions
– Startup characterization
Like traditional power analyzers, IntegraVision can provide you with fast and accurate
measurement of common parameters like power consumption and efficiency and harmonics.
Visualizing and measuring dynamic conditions is important due to the increasing complexity of
control systems. IntegraVision can capture voltage, current and power waveforms over specific
periods of time. Placing cursors on the captured waveforms will enable you to visualize and
measure power consumption across a wide range of modes, from sleep to full activity, and all
the transient states in between.
IntegraVision’s single-shot measurement capability simultaneously captures voltage and
current, so you can visualize and measure critical one-time events, like the response of
your device to dynamic conditions, such as an unstable AC line. Using trigger-in, you can
synchronize your AC source with IntegraVision and capture power converter response to cycle
dropouts, line spikes, sag/surge and other AC line distortions. Similarly, you can capture your
DUT’s response to other time-varying events, like a step change in load or other dynamic
loading conditions. You can also visualize and measure events like start-up, in-rush current,
and calculate i2t for fuse sizing. IntegraVision’s direct high-accuracy measurement of your
converter’s output allows you to visualize and measure transient response, settling time,
and other power supply performance characteristics. These measurements pose challenges
for ground-referenced 8-bit or 10-bit scopes which don’t have enough vertical accuracy or
resolution to measure load regulation or to resolve narrow settling bands.
