Reverse recovery is also measured using a double pulse, but the load inductor is now switched across T2
and T1 is used to charge the inductor. After T1 is turned off, the body diode in T2 conducts. When T1 is
turned on again, the reverse recovery of T2 can be measured.

条件：setup in the fixture. To correlate the timing of each measurement probe, de-skew is also implemented.
Keysight’s PD1500A uses many common measurement practices. Some attenuation probe errors are
eliminated by compensating the passive probes and adjusting the offset of the differential probe as
recommended. Care was taken to minimize parasitic capacitance and inductance when laying out the DPT
Gain and offset errors for each oscilloscope channel/probe can often lead to errors in the DPT
waveforms, which will impact the extracted parameters. The PD1500A incorporates an automatic
calibration technique that uses a known-good accurate, internal system voltage standard to measure and
characterize each oscilloscope channel. Gain and offset errors are compensated for to provide more
Current Shunt Compensation
条件：accuracy of ID / IC measurements, resulting in a more accurate extraction of DPT parameters.
Current shunts can have poor bandwidth and inconsistent performance from shunt to shunt. Keysight
characterized a popular coaxial shunt with a network analyzer and found a wide variability in bandwidth,
from ~25 MHz to 300 MHz. This variability significantly impacts dynamic testing of higher-speed WBG
power devices. Every PD1500A system is supplied with a pre-compensated current shunt that is used for
ID / IC measurements. The compensation applies the inverse of the shunt’s transfer function to the output
signal measured to flatten the response across the bandwidth of interest. This method increases the
Your safety is critical when testing power semiconductors. Keysight designed multiple safety features into the PD1500A to enhance
your safety. The test environment is covered by a transparent hood, protecting the user from contacting high voltages. When >
42V is energized, the hood is
locked and the red light is illuminated
For further protection, the PD1500A provides an Emergency Off Operation (EMO) button to disconnect
high voltages when pressed

PD1500A Overview and Basic Operation
The PD1500A is designed to be modular, allowing for a variety of devices (SiC, IGBTs, Si MOSFETs and
GaN) and characterization tests (DPT, reverse recovery, gate charge). The system provides complete
DPT characterization and parameter extraction for discrete power semiconductors, supporting maximum
power operation at 1.2 kV and 200 A.

The PD1500A fixture allows TO-247 (3- or 4-pin) or SMD packages to
interface with the system. Connections for de-skew and AutoCal are
readily available. When high-current and module testing is included,
the system will scale to the appropriate size for the DC-link capacitor
and load inductors. When high performance GaN testing is included,
the gate drivers, clamp circuit, DC–link capacitors and load inductors
