Double Pulse Testing, Three Ways: From Manual Bench to Automated Production Cell at PCIM

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...

No Bulk Capacitor, No Problem: Inside TI's Single-Stage Micro Inverter Demo at PCIM

No 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...

The World's Only Fibre Optic Isolated Oscilloscope: Why Cleverscope CS548 Exists and What It Solves

The 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...

Adaptive Gate Current Shaping: How Bosch EG120 Solves the Parallel SiC-MOSFET Balancing Problem

Adaptive 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...

When an Oscilloscope Becomes a Motor Drive Analyzer: The Case for Application-Specific Measurement

When an Oscilloscope Becomes a Motor Drive Analyzer: The Case for Application-Specific Measurement

The MDA 8208HD doesn't call itself an oscilloscope. It's a Motor Drive Analyzer — and that distinction defines everything: 8 channels for three-phase systems, automated harmonic analysis, and correlated time-frequency...
