High-Side Double Pulse Switching Loss with IsoVu Current and Voltage Probes

For engineers working on wide bandgap SiC and GaN power converters, this video demonstrates making accurate high-side double pulse measurements. Seamus Brokaw, Applications Engineer, uses an IsoVu™ Isolated Current Probe, Isolated Voltage Probe, and a 5 Series B MSO running Double Pulse Testing application software. He explains the test setup, probe choices, and deskewing, then demonstrates a double pulse test to determine switching losses, followed by key parameters like di/dt, peak drain voltage, dV/dt, and reverse recovery measurements.
