Micro Surge Filter TWM Series
Recent advances in power electronic switching device technology have resulted in dramatic improvements and cost reduction of pulse-with modulated AC adjustable speed drive. Concomitant with the better performance enabled by the high switching speed and increased switching frequency they have also raised several concerns related to the consequences of high speed switching.
One of these concerns is the over-voltage that appears at the motor terminals due to the impedance mismatch between the power cable and the motors.
Micro surge filter is proven economical devices to improve inverter-fed motor reliability, increase motor life, and solve long lead over voltage problems.
- Efficient reduction of high output voltage dv/dt from IGBT motor drives.
- Protection of motor coil insulation from premature aging and destruction.
- Significantly increased service life of electric motors.
