In-phase current-sense reference design for 230-VAC motor drives using hall-effect current sensors
Description
This reference design features the Hall-effect current sensor: TMCS1100: that can measure currents with an absolute error of < 1% (–40 to 125 °C) and provide a working isolation voltage of up to 600 V. The low-resistance in-package current sensing element and lack of need for high-side power supply enable a compact and efficient current sensing solution for precise motor torque: speed: or position control. The inverter power stage is comprised of 600-V LMG3411 Gallium Nitride (GaN) power modules enabling further size reduction and efficiency improvement for the next-generation of motor drives.
Features
- Accurate current sense (Accuracy stability over a wide temperature range eliminates the need for external offset or drift compensation.In-package sense element: and a lack of need for high-side power supply enable a small footprint: low-cost current-sense system.Efficient and compact inverter power stage is based on 600-V LMG3411 GaN power modules with integrated gate under-voltage: device overcurrent: and over-temperature protection.
Applications
- AC drive power stage module
- HVAC controller
- Servo drive power stage module
