Servo Drive Energy Recovery

The servo drive energy recovery system feeds back energy to the grid when the motor is braking rather than dissipating the braking energy into heat. A high efficiency DC/AC three-phase fast switching isolated power stage with accurate current/voltage sensing and sophisticated control enables power efficient and green energy servo drives. The servo drive energy recovery system requires basic or reinforced isolation with high EMC immunity depending on the grid voltage. TI reference designs and solutions help solve these system design challenges.

• Basic and reinforced capacitive isolation technology with industry leading CMTI, lowest propagation delay and high EMC immunity
• Isolated and non-isolated IGBT/SiC/GaN FET gate driver with high CMTI, lowest propagation delay and built-in protection
• Accurate current/voltage sensing with isolated precision, low-drift delta-sigma modulators and amplifiers for shunt, hall-effect or flux-gate sensors
• Efficient isolated and non-isolated power solutions supporting all typical power supply topologies
