To say the COVID-19 crisis has caused disruptions in the global supply chain would be an understatement. In fact, it has undoubtedly unveiled the fragility of current global trade and highlighted the vulnerabilities in the west’s dependence on China. This has caused many manufacturers to reexamine their supply chain strategies and consider a move towards a more resilient approach.

Two trade strategies have been gaining momentum throughout the course of this pandemic. The first is the “China plus-1” concept. This approach retains sourcing in China but also diversifies your business by importing from other Asian countries as well. This strategy has been growing over the past several years but rose significantly as of late with the primary benefactors being Taiwan, Thailand, and other countries with stable governments and close proximity to China.

Another strategy that manufacturers are turning to is “Nearshoring.” Nearshoring is a tactic western importers are turning to which moves the supply chain from Asain countries to facilities closer to the final destination such as Mexico. With the ever-growing costs associated with doing business with China, Latin American countries are shrinking the cost gap as they also have a significant advantage when it comes to the high costs and long lead times that are associated with overseas freight.

Over the 40 years that Pacific Transformer has been in business we have witnessed and endured many crises such as multiple economic recessions, dock strikes, and trade wars. Each one of these events has had us look at our own vulnerabilities and come up with solutions that keep our customers isolated. This has led us to create a multi-pronged supply chain that invests in multiple global production facilities including in China, Thailand, and Mexico. Additionally, and most importantly, we have always maintained and invested in our US production plant. This has offered us a tremendous amount of flexibility ensuring our customers are protected from most supply chain disasters.

When it comes to quality, some come close to our high standards but no one can beat us. We have spent decades devising a quality management system that ensures the highest standards possible. These quality standards have been independently audited and certified by the most demanding auditors and agencies. Organizations such as ISO, the International Aerospace Group and NSF International. We are also qualified by UL, CSA, ETL and TUV. We have over one million of our products on various military apparatuses. Medical equipment, satellites, railroad safety and traffic control all require the highest level of quality because there simply can be no failure.

We asked one of our lead engineers, what are the essential questions you ask when designing a custom power transformer?

He broke down these questions into five primary categories that cover 90% of the applications

1 – The Type of Transformer

What type of transformer does it need to be? The most common are:

• Single Phase
• 2-Phase
• 3-Phase

Don’t worry; we specialize in the not-so-common types as well.

2 – Primary (The Input Section)

• What is the input voltage?
• What is the input current?

3 – Secondary (The Output Section)

• What is the desired output voltage?
• What is the desired output current?

If the secondary is DC, what is the rectifier topology? The most common are:

• Full Wave Bridge
• Bridge
• Center-Tapped
• Single Phase

4 – Finish (The Connectors)

What type of connectors do you need for your application? The most common are:

• Wire leads
• Terminal Block
• Solder Lugs (Used primarily on PCB boards)
• Copper Terminals

5 – Geometry (The Size)

What is the desired size or the space restrictions of the transformer?

In more complex applications, there may be a few other considerations categories to discuss, such as:

Regulation

The voltage regulation of the transformer is the percentage change in the output voltage from no-load to full-load. Voltage regulation will vary as the power factor varies. The regulation is measured in percentage.

Temperature

• What is the ambient temperature range the power transformer will be working within?
• What is the maximum allowable temperature rise?
• Will there be any cooling?

Testing

Some applications will require additional testing to receive a particular certification. For example, many transformers built for defense require a MIL-SPEC certification, which subjects random samples to vibration testing.

Regardless of your project’s complexity, our engineering team has the expertise to design the ideal solution for your application.

High-frequency transformers aren’t a new concept. In-fact they have been a staple in radio frequency circuits, amplifiers, antennas, and transmitters. However, in today’s high-tech world of internet-connected mobile devices, renewable energy, and electric vehicles, the need for high-frequency transformers has grown exponentially over the past decade. Unlike low-frequency transformers, they come with additional design considerations.

In your typical line-level transformer operating at 60hz (low frequency), it will generally use a laminated iron core as the waveform has no problem saturating through. However, as the frequency is increased, an iron core will start to experience an increase in hysteresis losses, also known as the “rubbing effect.” Essentially, the “faster” you magnetize and demagnetize an iron core, the more heat is generated, which at a certain point becomes incredibly inefficient – this is where a different material such as a ferrite core begins to make sense. Ferrite losses are significantly less; however, it comes with a tradeoff. Ferrite cores offer less mechanical strength and become more brittle the larger they become. Therefore, the type of application, as well as the power levels required, will ultimately determine whether or not a ferrite core is viable.

The good news is there are several other advanced materials other than ferrites that can be used as an alternative, but they too have their unique tradeoffs. That being said, there is no one-size-fits-all approach when it comes to high-frequency transformers – this is where our expertise comes into play. Our engineers have been designing high-frequency transformers for decades and know how to design a product that is efficient and highly reliable. In-fact, our high-frequency designs are used in mission-critical military and aerospace applications. The next time you are in need of a complex transformer, start with Pacific Transformer.
