Planar Magnetics   

Many of the active power components for the electronics are available and are being designed in.  The passive power components are another story. The power magnetic components must be small, lightweight, and meet the environmental requirements. Magnetic components are made of wire or are wire-free. Planar Magnetic components have advantages compared to wired magnetic components, and designers should note these advantages when evaluating the technology for future designs.

Planar Magnetics utilize copper stampings and multilayer boards in a serial or parallel combination to achieve the required turns and power density.  Multiple outputs and 1000Amps in a single output are possible.

Planar Transformers and Inductors from Payton
will provide solutions to:

1. Unparalleled working frequency range from 50khz to 3Mhz
2. Dramatically reduced size and weight. (approx. 5g per 100W)
3. High Efficiency, typically 97 to 99.5%
4. Unmatched parameter Consistency
5. Low Leakage Inductance. (less than .2% for ungapped cores)
6. Cost Effective Prices
7. Minimum Electromagnetic Interference
8. Operating temperature Range from -55C to +130C
9. 5W to 20,000W range in one unit
10. 4kV primary to secondary dielectric isolation when needed
11. 6-16mm creepage and clearance distance between primary and secondary windings
12. Solutions for ALL SMPS topologies
13. Lower noise than a conventional magnetic (Slighter higher winding capacitance butbetter winding shielding and much lower leakage inductance) ‏

What are the design requirements an Engineer looks for?

First is efficiency.

Power planar magnetics are 99.0% efficient at converting the input energy to the output energy.  In comparison, wired magnetic components have a conversion efficiency of 90%.  The high efficiency with the combination of conduction cooling reduces the internal temperature of the power box, dramatically improving the MTBF of the system.

Second is size.

Unlike wired magnetic components that are usually restricted to sizes - particularly the height - power planar magnetics can be “squashed” to reduce their height with an increase of their base area, for optimum cooling, so the magnetics fits into a minimum space.

Third is temperature.

Power Planar magnetics operate in the temperature range from -55 degC to + 150 degC.  In addition the conduction cooling offered by the inherent mechanical characteristics of the planar construction can offer thermal impedance as low as 0.5°/W.

Fourth is weight:

Power Planar Magnetics can reach a weigh of approximately 10g per 100W. 

Fifth is power.

Power Planar Magnetics supply 5W to 20,000W in one unit. Payton has the technology and the know how to provide a typical hybrid power transformer for a full bridge ZVT application, at 100khz and 7KW output power, in a 2.2”x2.2”x.62” package at less than 200 grams. The same type of transformer using a conventional wired type will take 9 times the volume and 5 times the weight.

Sixth is repeatability.

With pre-tooled windings and well defined geometry, electrical parameters are predictable and repeatable. An engineer does not have to be concerned any more if the leakage inductance or the winding capacitance will change with time or if it will vary significantly from lot to lot.  Experience with wired magnetic components has shown that many of the parasitic characteristics change from lot to lot and with time, and these changes will have an effect on the common mode noise and EMI.

With these characteristics and advantages, more designers are looking to power planar magnetics for their designs. Payton is committed to helping designers use power planar magnetics to achieve these improvements.
 
One example of a custom design is a 36kVA power Planar application with 600Amps rms primary current and 230Amps secondary current in a 140mm(L)x90mm(W)x40mm(H) thermal package with 0.66ºC/W thermal impedance designed specifically for a cool plate high vibration environment. With 120watts of dissipation this design has an efficiency of 99.67%.  The switching frequency is 60khz and the topology is push-pull.

This is an example of a Filter Planar Inductor using flat magnet wire, ferrite planar cores and an aluminum clasp for mechanical mounting and best thermal performance.

Editor’s note: Two companies, SL Power Electronics and Venture-Q, LLC, were recently approved for membership. Their profiles will be included in the next issue of the Update.

One of the recipients was B. Jayant Baliga, Distinguished Professor at North Carolina State University. Jay received this prestigious award "For development and commercialization of the Insulated Gate Bipolar Transistor and other power semiconductor devices that are extensively used in transportation, lighting, medicine, defense, and renewable energy generation systems".

This is the highest honor one gets in the United States for technological achievement.  Prof. Jay Baliga is a well known figure in the field of power electronics and often referred to as the "Father of the IGBT". He received this medal for his pioneering research at GE's Global Research lab in Schenectady, NY in the early 80s that led to the invention of Insulated Gate Bipolar Transistor (IGBT). Jay's accomplishments and corresponding list of the awards are numerous, but this honor stands out because it has been given by the President of the Unites States and selected from the entire field of technology. Prof. Baliga is a Distinguished University Professor of Electrical and Computer Engineering at North Carolina State University and is also founding director of the Power Semiconductor Research Center.

On a broader scale, this is a great honor not only for Prof. Jay Baliga, but also for the field of power electronics - which is usually in the shadow of the more popular ICs/semiconductors and computers/systems fields. Prof. Baliga's selection acknowledges the contribution of power electronics to the overall welfare of electronics in the context of science and technology.

The invention of IGBT is even more important today as energy conservation has become one of the central issues of our time encompassing many social, cultural and technological boundaries. The invention and commercialization of IGBT technology has led to its extensive use in the consumer, industrial, lighting, transportation, medical, renewable energy, and many other sectors of the economy. It has enabled energy savings in countless ways resulting in huge cost savings to consumers, and reduction of world-wide carbon dioxide emissions.

The National Medal of Technology was created in 1980 by the United States Congress under the Stevenson-Wydler Technology Innovation Act. It was a bipartisan effort to foster technological innovation and advance the technological competitiveness of the United States in the international arena. The first National Medals of Technology were awarded in 1985.

To understand the total context and importance of this award, one has to look at some of its past recipients which include:

• Steve Jobs & Steve Wozniak (1985:  For the development of personal computer: Apple Computer),
• Robert Noyce (1987: For the development of Integrated Circuits-IC: Intel Corp.),
• David Packard (1988: For the leadership in industry and government: HP)
• Jack Kilby (1990: For the development of Integrated Circuits-ICs: Texas Instruments-TI: Jack Kilby also won the Nobel Prize for Physics in 2000. He was credited with Robert Noyce for the development of Integrated Circuits)
• Gordon Moore (1990: For the development of Integrated Circuits-ICs and Microprocessors: Intel)
• Bill Gates (1992: For the vision on universal computing: Microsoft)
• Ken Olson (1993: For the development and use of computer technology: Digital Equipment Corporation-DEC)

Prof. B. Jay Baliga is among these distinguished individuals and he is the only individual, so far, to receive the award in the field of power electronics or power semiconductors.

Receiving the National Medal of Technology and Innovation is a unique event and I feel that Prof. Baliga should be honored and recognized for this achievement at the start of the Plenary Session at APEC 2012.
