Our design is one of the top most product with high efficiency to provide a Sine Wave output voltage when driven from Variable Frequency Drives or other types of PWM inverters with switching frequencies from 2kHz to 8kHz. These filters are low pass frequency filters, which convert the rectangular PWM output signal of motor drives into a smooth sine wave voltage with low residual ripple. We, TS International are recognized as sine wave filter reactor manufacturers in Bangalore, India.
Variable Frequency Drive (VFD) applications, Sine Wave Filters eliminate the problem of motor/cable insulation failures, heating, and audible noise. Sine Wave Filters also reduce electromagnetic interference (EMI) by eliminating the high dV/dt associated with inverter output waveforms.
In Bangalore, with over 6 decades of experience in electrical domain, we have the expertise to design and manufacture sine wave filter reactor which are highly reliable, sturdily constructed, perfect on finishing, advance in technology, user friendly, effective to use and many more features.
For alternative energy applications, such as wind driven generators, where an inverter is used to return power to the utility distribution system through a step-up transformer, these filters meet the standards.
