Power Analyzers for Accurate Power Measurements
Power analyzers are designed especially for making accurate power
measurements on a wide range of power conversion systems: from cell-phone
chargers to 1000 kW grid-connected inverters. PA3000 Series Power Analyzers
can be configured with one to four input channels for testing three-phase devices,
or for testing input and output power simultaneously. The PA3000 also includes
special modes for testing efficiency and standby power on power supplies,
PWM motor drives, LED drivers and lighting ballasts. The PA1000 is designed
for precision power analysis and testing power consumption on single phase
applications such as appliances, power supplies and hand tools. Both analyzers
enable you to measure conversion efficiency and perform pre-compliance testing.
Power Supply Switching Analysis
A significant amount of power is lost during FET switching, and many Tektronix
oscilloscopes can be outfitted with special power analysis software to quantify
this important switching loss. For example, an MSO/DPO5000B equipped with
DPOPWR power analysis software can measure switching loss, magnetic loss,
safe operating area and harmonics.
IsoVu isolated measurement systems combine bandwidth up to 1GHz, common
mode rejection of 10000:1 and complete optical isolation to enable accurate
measurements on next generation GaN and SiC switching devices.
Making High-speed Current Measurements
Making accurate current amplitude measurements even at high slew rates is
critical to achieving maximum power efficiency. Tektronix current probes provide
industry-leading measurement sensitivity down to 1mA and bandwidths up to 100
MHz. When paired with today’s Tektronix oscilloscopes the latest current probes
automatically scale the readings to amperes and provide status information right
on the oscilloscope display. The IsoVu isolated measurement system can also be
used to measure current across shunt resistors up to 1 GHz.
