Double Pulse Testing, Three Ways: From Manual Bench to Automated Production Cell at PCIM
The double pulse test is the same. The infrastructure around it has split into three distinct product categories: precision bench characterization (R&S MXO5), automated production testing (iPE cell), and development...
WeiterlesenNo Bulk Capacitor, No Problem: Inside TI's Single-Stage Micro Inverter Demo at PCIM
A single-stage AC/DC micro inverter eliminates the intermediate 400V bus capacitors that limit the service life of conventional two-stage designs. The TI TIDM-01035ME2 at PCIM showed what that looks like...
WeiterlesenTwo Oscilloscopes, One Wolfspeed Board: How Keysight Tackles the High-Side Measurement Problem at PCIM
One Wolfspeed SiC evaluation board. Two Keysight oscilloscopes — 1 GHz 14-bit on the left, 6 GHz 16-bit on the right. Same DUT, different measurement questions, different instrument tiers. The...
WeiterlesenThe World's Only Fibre Optic Isolated Oscilloscope: Why Cleverscope CS548 Exists and What It Solves
How do you measure the high-side gate voltage in a GaN inverter when the switching node swings at 100 V/ns? The Cleverscope CS548 uses fibre optic isolation — 2kV between...
WeiterlesenAdaptive Gate Current Shaping: How Bosch EG120 Solves the Parallel SiC-MOSFET Balancing Problem
Two SiC MOSFETs in parallel will never have exactly the same threshold voltage. That nanosecond difference creates transient current imbalance that degrades reliability over a vehicle's lifetime. The Bosch EG120...
