Description
TDSPWR3 power measurement and analysis software
transforms Tektronix digital oscilloscopes into sophisticated analysis
tools that quickly measure and analyze power dissipation in power
supply switching devices and magnetic components, and then generates
detailed test reports in customizable formats. TDSPWR3, used with
a Tektronix TDS5000B, TDS7000/7000B, CSA7000 Series or TDS6000B models
oscilloscope and differential voltage and current probes, forms a
complete measurement system for power supply design and test.
To improve the efficiency of switching power supplies with increased
power densities, designers need to analyze power dissipation and characterize
transitions at higher switching frequencies. Using TDSPWR3’s unique
switching loss and B-H analysis features, you can measure switching
and magnetic device power dissipation with a touch of a button. Tektronix
oscilloscopes’ high bandwidth, high sample rate and deep memory, combined
with the TDSPWR3, enable you to efficiently and accurately characterize
switching power supplies by measuring power loss at the switching
device and magnetic component. Reliability at the component level
of the switching power supply can be analyzed using Safe operating
area with mask test capability and measuring the peak flux density.
With the current harmonic standard (EMC) being imposed worldwide
to maximize the efficiency of the existing total generation capacity,
compliance to the IEC EN61000-3-2, EN61000-3-2 AM14 is critical. Reduce
your development and testing time by using the precompliance testing
capability of TDSPWR3 to test power supply designs to these standards
from your bench.
TDSPWR3 enables you to set units and scale
factor for Tektronix current and voltage probes to read the result
in the right unit. Automated deskew capabilities help you to get accurate
results.
