Using Optocouplers for Safety and Protection in Motor Drives and Inverters
Motor drives and inverters work in high voltage domains and require safety isolation and protection to meet regulatory requirements. Optocouplers have been the defactor standard in providing this function for over 3 decades and have their own optocoupler-only safety standard IEC 60747-5-5. Join Avago Technologies in this Webinar to learn about Optocoupler Isolation Advantages, as well as how optocouplers can help to meet safety and protection requirements in motor drives and inverters designs.

Driving and Protecting IGBTs in Inverters
The ACPL-339J is the industry's first dual-output gate drive optocoupler, uniquely designed to support a MOSFET buffer to maximize gate drive design scalability and power conversion efficiency. It also offers a compact and cost-effective solution for protecting the IGBT with integrated features like UVLO, short circuit detection and "soft" IGBT turn-off. Power designers doing motor drives, industrial and renewable energy inverters, and switching power supplies should attend to learn how to drive IGBT for better power conversion efficiency, how to protect IGBT to improve overall system reliability and the advantages of the ACPL-339J in achieving system design scalability, efficiency and reliability.

Gate Drive Design Scalability and Power Conversion Efficiency
Expanding upon Avago’s earlier generations of market-proven smart gate drive optocoupler devices, the new ACPL-339J is designed to further maximize gate drive design scalability for motor control and power conversion applications ranging from low to high power ratings. Uniquely designed to support MOSFET buffer of various current ratings, ACPL-339J makes it easier for system engineers to support different system power ratings using one hardware platform by interchanging the MOSFET buffers and power IGBT/MOSFET switches. More importantly, these changes can be made without redesigning the critical circuit isolation and short circuit protection.
Designing with Current Sense optocouplers in Motor Drive systems
In Motor drive applications accurate phase Detection of the Motor Current and transfer of data to the Controller is very important. Isolation Amplifiers work with the SHUNT RESISTOR, especially in noisy environments to provide accurate Current Measurement. The Device includes a built-in AD converter, combined with robust and reliable optical coupling technology to achieve high gain accuracy and common mode noise rejection. Typical applications include Motor phase Current sensing, DC Bus Current detection, inverter Current sensing, and Universal Voltage Detection. Compared with the conventional Hall effect Sensors or Current transformers, isolation Amplifier Detection scheme provides a Smaller, Higher Precision, Lower cost Solutions.
