Teledyne LeCroy WS510-PWR - Power Analysis Option for WaveSurfer 510

Analyze power device performance while the device is operating in circuit. Easily make switching loss, dynamic-on resistance, dv/dt and di/dt measurements. Quickly view safe operating area and B-H hysteresis curves.

Power Device Analysis

Power Device Losses

Turn-on, turn-off and conduction zones are identified with a colorcoded overlay, power losses in these zones are automatically measured and displayed. Losses associated with the switching, conduction, and off-state are measured independently and displayed along with the sum of selected loss types.

Switching transitions, conduction losses and off-sate losses are color-coded and automatically calculated. Measurements are displayed as energy (joules), mean or peak power (watts). For discontinuous supplies, off-state loss provides an excellent tool to fine adjust a current probe’s DC offset and improve measurement accuracy.

Safe Operating Area

Gain insight to circuit performance by seeing SOA plots to look for violations in the first cycles after an event or over long time periods. Finding SOA violations that occur for only a few cycles after an event, such as short circuit or startup, can be problematic. These violations often go undetected, and degrade the device over time.

Using the long record length and fast processing of Power Analyzer, SOA display on very long records, confirm turn-off voltage and current limits are not exceeded.

B-H Hysteresis Curve

View the behavior of a magnetic device while it operates in circuit. Dynamic circuit changes show resulting magnetic saturation and operating region.
