Sustainable Energy Issued Pulsed-Step Inverter Patent

October 22, 2003 by Jeff Shepard

Sustainable Energy Technologies Ltd. (Calgary, Alberta, Canada) announced that the US Patent and Trademark Office has issued a new patent on its pulsed-step power inverter technology. The patent expands existing patents issued to Sustainable Energy in March of 2001, further protecting the intellectual property that is central to the company’s integrated energy management and power-conditioning systems.

Sustainable Energy’s patented inverter technology is the first to directly link the renewable energy source to the power grid in a single power-conversion step, reducing complexity and cost, while increasing overall system efficiencies and reliability.

"Our pulsed-step technology is a departure from conventional approaches to power conversion and results in a much simpler, less-complex design than competitive products currently in the market," explained Brent Harris, director of technology development. "Key to the successful application of the pulsed-step technology is a focus on configurable software control that controls the output waveform in real time, enabling the inverter to implement the control algorithm most appropriate to each renewable energy resource."
