Low Harmonics to the Grid. True Sinewave to the Motor
Instead of adding external filters and special motor protection, our SiC-based architecture delivers clean power at the source—fewer components, less stress, more predictable performance.
ABOUT
The Clean Power VFD was built to solve the problems conventional drives create.
Instead of adding external filters and special motor protection, our SiC-based architecture delivers low harmonics to the grid and a true sinewave to the motor—at the source. Fewer components. Less stress on equipment. More predictable performance.

The Evolution of Motion: From Invention to Clean Power
1834
The Birth of the Motor
The first practical electric motors emerge, converting electrical energy into mechanical work and powering the Industrial Revolution.
1888
The AC Revolution
Nikola Tesla patents the AC induction motor. Rugged, simple, and efficient — but with one major limitation: fixed speed. For nearly a century, speed control remains mechanical and inefficient.
1960s
The Dawn of the VFD
The first Variable Frequency Drives (VFDs) arrive. For the first time, AC motor speed can be controlled electronically by manipulating frequency — but it introduces a hidden tradeoff.
The Industry Response
To protect equipment, manufacturers add mitigation devices — sinewave filters, line reactors, common-mode chokes, specialized VFD cables. Motor control advances, but complexity multiplies.
2018
The SmartD Breakthrough
SmartD rethinks motor control using Silicon Carbide (SiC) technology and multi-level power conversion.
Instead of mitigating the damage, we eliminate it at the source — delivering low harmonics to the grid and a true sinewave to the motor. No bulky external filters. No layered fixes.
2026
Global Impact & Proven Performance
Today, SmartD Clean Power VFDs operate in hundreds of installations worldwide — from heavy industrial facilities to municipal infrastructure and commercial agriculture.
They deliver low harmonic distortion, near-unity power factor, and motors that run cooler and last longer — without external mitigation equipment.
OUR PRODUCTS
SmartD Clean Power VFDs combine SiC technology, active front end architecture, and integrated filtering to deliver < 3% THDi on the line side and a true sinewave on the motor side — in one compact drive. No mitigation layers. No added complexity. Just clean power.

WHY CLEAN POWER VFD?
Ultra Low Harmonics
Clean Power VFD offers ultra-low harmonics, reducing electrical noise and increasing energy efficiency for your equipment.
Filter-less
Clean Power VFD is filter-less, providing cost-effective and maintenance-free operation for your equipment.
Active Front End
Clean Power VFD features an active front end, enabling power factor near unity, ultra-low harmonics and regenerative braking for improved energy efficiency.
Space divided by 2
Clean Power VFD being of compact design, and eliminating the need for filters, saves up to 50% of space and simplifies equipment wiring.
Clean Signal
Clean Power VFD using the last technology of electronic power components, patented algorithm and embedded filters, it provides motors with a clean sine wave.
Extended Motor Life
Clean Power VFD’s advanced performances reduce motor insulation stress, bearing damage, and electrical noise for a longer motor lifetime.
APPLICATIONS
Water & Wastewater
From lift stations and booster pumps to aeration blowers and sludge handling systems, water and wastewater facilities depend on reliable motor control in electrically sensitive environments. SmartD Clean Power VFDs minimize harmonics at the source and deliver a true sinewave to the motor, reducing transformer heating, nuisance trips, and motor stress — even over long cable runs common in pump stations. Ideal for retrofit projects where space is limited and compliance with IEEE 519 at the PCC is critical.
Data Centers
Data centers demand power quality, stability, and predictable performance. Cooling towers, CRAH/CRAC units, condenser pumps, and chilled water systems must operate without introducing harmonic distortion or electrical noise into sensitive infrastructure. SmartD’s low THDi active front end and pure sinewave output help protect upstream transformers and downstream motors while maintaining near-unity power factor — reducing electrical penalties and lowering infrastructure stress in mission-critical environments.
HVACR
Commercial and institutional HVAC systems rely on fans, pumps, and compressors operating across varying loads. Traditional PWM drives can introduce harmonics and voltage spikes that shorten motor life and increase maintenance costs. SmartD Clean Power VFDs provide precise speed control with low harmonic distortion and reduced motor heating, allowing standard motors and cables to be used without external sine filters — simplifying installations in space-constrained mechanical rooms.
Oil & Mining
Mining operations and oil & gas facilities often operate in remote, harsh, and generator-driven environments where power quality and reliability are essential. Long motor cable runs, heavy loads, and fluctuating supply conditions increase the risk of voltage spikes and bearing damage. SmartD’s integrated sinewave output and low-harmonic front end reduce electrical stress on motors and upstream equipment while eliminating the need for bulky mitigation hardware — improving reliability and reducing maintenance in demanding conditions.
Food & Beverage
Food and beverage plants require reliable, hygienic, and space-efficient electrical systems for pumps, conveyors, mixers, refrigeration compressors, and packaging lines. Electrical noise and harmonic distortion can disrupt sensitive automation equipment and increase transformer heating. SmartD Clean Power VFDs reduce harmonic impact on the facility grid and deliver smooth motor operation, supporting cleaner electrical rooms, reduced maintenance, and longer motor life — without adding external filter cabinets.
