We engineered the Clean Power variable frequency drive combining features that are normally found separately in multiple different products. We do this all while keeping product cost lower and product volume much smaller than a conventional drive.
SmartD Technologies Inc. produces advanced motor control products based on 3 core technologies that complement each other to bring the best Return On Investment:
The emergence of a new generation of power electronics transistors dubbed wide-bandgap (WBG), such as Gallium-Nitride (GaN) and Silicone Carbide (SiC) transistors, offer new capabilities based on their properties of low RdsON, fast switching, and low switching loss.
When these properties are applied to motor drives, they can improve energy efficiency and signal quality. In the field, they can result in high motor efficiency, fast control response, lower motor torque ripple, smaller low cost filter size, and much more.
The use of wide-bandgap and high switching frequency comes with its own technical challenges. Getting these results is not as simple as pushing technology onto a product.
Precise control and modulation algorithms are needed to take full advantage of WBG and MLI applied to motor drives.
SmartD’s strong IP portfolio of control and modulation algorithms reduce the size and number of passive elements needed in inverters while enabling sensor-less VFD control. This decreases the cost of the product and increases its reliability.
WBG transistors do not necessarily generate benefits everywhere they are used. Using our innovative modulation method enables SmartD to use WBG transistors optimally. They are only used where product design requires it, thereby getting the most out of their properties while minimizing cost.
