Measurement Challenge

Switching Loss

Most switching loss occurs during transitions Minimize transition time to

reduce switching loss

Must be able to measure turn-on, turn-off and cycle power loss

Most oscilloscope solutions don’t measure to this level of detail

TDSPWR2 Solution

Switching Loss

TDSPWR2 automatically computes the switching loss at Turn-on, Turn-off and for the entire cycle at the switching device

Min, Max and average values computed for trend data on switching loss over time in a dynamic load situation

HiPower Finder feature analyzes pinpoints areas of instantaneous power dissipation

Measurement Challenge

Core Loss & B-H Analysis

Magnetic components designed to enhance performance may cause power dissipation

Important to know the operating limits of these components in order to determine safe operation of the power supply

No current oscilloscope solution can provide this data

TDSPWR2 Solution

Analysis of Safe Operating Areas

TDSPWR2 and a DPO provide the long record length and automatic measurements to make this task fast, easy

Long record length of scope captures entire event

Automatically measure and determine safe operating area Locate and analyze the

linkage between safe operating area and the waveform in the time domain
