About SmartD Technologies SmartD Clean Power VFD is a new class of variable frequency drive built on silicon-carbide (SiC) technology. Unlike traditional PWM drives, it delivers a true sine-wave output—eliminating harmonics, dv/dt stress, and the need for external filters. For HVAC systems, this means quieter motors, longer equipment life, simpler retrofits, and lower total installed cost—without sacrificing efficiency or control. SmartD Technologies produces the smallest, fastest, smartest variable frequency drive on the market: the Clean Power variable frequency drive. The Clean Power Variable Frequency Drive (VFD) is a highly efficient product designed to control motor speed and torque by producing a pure sine wave which helps to minimize harmonic distortion and improve the lifespan of equipment. The Clean Power VFD is suitable for a wide range of industries, including infrastructure, utilities, agriculture, mining, transportation, marine, water & wastewater and more. By improving motor efficiency and reducing wear and tear on equipment, the Clean Power VFD helps businesses save energy, lower costs, minimize their carbon footprint and achieve their goals of maximizing productivity and efficiency.
