The 3 Types of Maintenance Approaches for Industrial Rectifiers

When it comes to preventative maintenance for industrial rectifiers, there are three levels that we most often see. By understanding these three levels of preventative maintenance and determining what category you fall into, you can begin thinking about how you can adopt new a higher-tiered strategy to save money and become more active rather than reactive.

Level I: Reactive Maintenance 

The reactive form of preventive maintenance is akin to going in for an oil change every 3000 miles. You do it because that’s what you’re told to do. You don’t perform any checks or maintenance on your vehicle other than changing whatever the manufacturer tells you to change.

The reactive maintenance approach basically involves taking action only when a problem has arisen. “When your equipment is down and there’s flames and smoke and downtime, you call us to fix it,” says Dynapower’s Repairs Supervisor Remington Schieffer.

SCR vs. SMPS Rectifiers: A Maintenance Perspective

Recently, we covered the three main considerations to weigh when buying a rectifier. Now, let’s dive a little deeper and shed some light a common debate in the world of rectifiers. We’re speaking of course about SCR vs SMPS rectifiers. As you will see, the ultimate differences and similarities may surprise you.

First, let’s run through the characteristics of these two classes of rectifiers. A silicon-controlled rectifier (SCR) is a semiconductor power supply that meters electricity by opening electrical “valves,” working together as a team, to rectify electricity. The longer the “valve” is open, the higher the voltage leaving the rectifier will be.


SCR rectifiers are variable voltage DC power supplies that are low frequency, high ripple systems. These systems are rugged and have a history of durability in the market – a number of our customers have systems running after 40 or 50 years. They regulate and react steadily, carry a lot of power in big copper windings, and are fairly easy to troubleshoot with large, easy-to-identify components.

Passing of Dear Friend and Colleague Ken Ziemann

Ken Ziemann, our colleague, and friend passed away on August 9th. He was 62 … far too young to leave so soon. Ken had a long and amazing work life, virtually all of it spent in the world of large electrical equipment. He was a rare breed and we are proud that he spent his last years with us — his Dynapower family.

He leaves an amazing legacy. His memory as well as drive to keep every bit of information on design, test, and construction of his work is known by all who knew and worked with him. Drawings, designs, proposals, even test reports, were kept and cataloged. It is always amazing to learn their value now. We continue his tradition today; designing and building the next generation of high power transformer rectifiers.

Ken traveled the world, always willing and ready to go wherever the job required. He relished the opportunity to be with customers, many times knowing them for decades. Recently we learned of an opportunity to upgrade equipment that is 30 years old, still running but in need of modernization. Of course, the original equipment was designed, built, tested and started in the field by Ken. He had a deep passion for his work. He was proud of his designs and loved watching the team build what he designed, always there watching, teaching, making sure it was done right. His name was on every transformer, every big rectifier, and he was proud of that.

It was well earned.

A work ethic like what Ken brought every day is hard to find. He lived in actions, showing his team hard work and dedication — every day, day after day.

We will remember him.

We will miss him.

We will continue to value what he brought to us every day.

And, we thank him and his family for the time he spent with us.

and the entire Dynapower family.

Dynapower Awarded New Patent for Grid Resiliency Technology

Dynapower, the world’s leading independent manufacturer of energy storage inverters and fully-integrated energy storage systems, today announced that the United States Patent and Trademark Office has issued the company a patent for its Dynamic Transfer technology which enables grid resiliency for its utility and commercial & industrial customers. The patented technology enables the seamless transition of an energy storage system with a Dynapower inverter from grid-tied to backup battery power in the event of a grid disturbance.

“This technology enables our utility customers and their ratepayers to have increased energy surety and provides resiliency from energy storage systems using Dynapower energy storage inverters,” said Chip Palombini, sales manager for Dynapower’s Energy Storage Group.

Dynapower’s Dr. Apurva Somani, R & D Lead, and Palombini are inventors of United States patent 9.819,190. Dynamic Transfer was designed to address energy resiliency issues, and more importantly, to ensure power surety for utilities and commercial and industrial users of Dynapower energy storage inverters and systems.

This is critical as the Electric Power Research Institute estimates that the economic costs of power outages amount to about $120 billion annually in the United States.

“Dynamic Transfer can help reduce the economic impact of power outages significantly by providing facilities with Dynapower inverters and energy storage systems the ability to seamlessly transition to backup battery power during a grid disturbance,” said Adam Knudsen, president of Dynapower, adding: “This is critically important for many facilities where even a short interruption in power can result in lost data, production time or food spoilage. Dynamic Transfer ensures their critical processes continue without interruption of power during a grid disturbance.”

Dynapower inverters and energy storage systems featuring the now-patented Dynamic Transfer capability have been installed to help power island nations with 100 percent renewables as well as help reduce the electricity bills and provide critical backup power at colleges, resorts, malls, factories, breweries, wineries, and sports stadiums.
