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...

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...
