Frequently Asked Questions

What efficiency can be achieved with IXYS devices?

IXYS power semiconductors enable solar inverter efficiencies of 98-99% when properly designed. Key factors include: (1) Device selection - using low Vce(sat) IGBTs and fast recovery diodes minimizes conduction and switching losses

(2) Switching frequency - operating at 10-20kHz balances efficiency with filter size

(3) Thermal design - proper heatsinking maintains low junction temperatures for optimal performance

(4) Gate drive - optimized drive circuits minimize switching losses. Our reference designs demonstrate 98.5% peak efficiency at full load.

Target 98%+ efficiency with proper device selection and thermal design.

How do I handle thermal management for outdoor installation?

Outdoor solar inverter thermal management requires: (1) Heatsink design - use natural convection or forced air with adequate margin for 60°C ambient

(2) Device selection - choose IXYS devices with low thermal resistance and high temperature ratings

(3) Thermal interface - use high-quality thermal pads or grease

(4) Enclosure design - ensure adequate airflow while maintaining IP65 protection

(5) Monitoring - implement temperature sensing and derating. Design for worst-case conditions including direct sunlight exposure.

Design for 60°C ambient with adequate heatsink margin and proper enclosure ventilation.
