Text Book Solutions Lag Technology. Plitron brings original research and developments to custom magnetics.

Plitron has many years of experience and experience in developing customer specified magnetics beyond the realm of convention, and offers our customers advanced solutions through incorporation of our advanced technologies into your products.

Unlike most companies that design and produce custom magnetics, Plitron Manufacturing recognized the need for original research and experimental scientific development over the last two decades. Driven by market demand to provide intelligent efficient power solutions to new rapidly growing and evolving industries under adverse load and line conditions – which may not have even been in existence a decade ago – Plitron determined that solutions demanded today are not fully understood and not common book knowledge.

Plitron’s continuous research programs have resulted in a demonstrated scientific advancement over many companies, and the developed proprietary technology often forms the basis for unique solutions and total solutions to power problems. To serve the needs of our customers in this fast changing industry, Plitron has the capability and expertise to respond quickly with technically superior products, possessing a natural advantage in the market place.

Work with Plitron Engineers to Innovate Solutions for your Power Requirements

Hysterisis Curves Research can be conducted on contractual per project basis with customers, and we invite and technical discussions and proposals. Plitron’s research team, equipped with effective design tools, such as Three Dimensional CAE (Computer Aided Engineering) designed for solving magnetic models (see below, Plitron design tools, Lab Capabilities, Tests, and Measurements), encourages partnerships with customer’s engineers to form a strong and productive force to innovate and invent products to resolve power related issues, using the least amount of materials an labour, built into the smallest feasible envelope, and maintain all performance and regulatory specifications.

Plitron’s Transformer Based Technologies Offer An Elevated Technology Base – As a Starting Point

Bandwidth is addressed by harnessing inherent L, C, R Inrush Current Limiting becomes a transformer constant Removes Audible Noise under Adverse Line and Load Conditions Smart Offsetting Symmetrical Stray Fields Management High performance e-screen, minimum impact on other specs Smaller, lighter, smarter three phase power

Plitron has developed original transformer based technologies offers capabilities without the need for external primary circuit components. A discussion of these properties can be found on the Enhanced Technologies page. As a brief overview, the following key magnetic parameters can constitute design input variables – not external components.

The following technologies are now deemed as transformer design input criteria.

Plitron Design Philosophy is to Offer Transformer Based Solutions – Address the problem at the root.

New product design and development is more often than not a crucial factor in the survival of a company. In an industry that is fast changing, firms must continually revise their design and range of products. This is necessary due to continuous technology change and development as well as other competitors and the changing preference of customers.

Advanced Design Base Raises the Bar. After gaining an understanding of the problem, all magnetics design starts in the same place.

Although the crucial first step in magnetics design can seem superficially simple and arbitrary; selection of core material, dimensions, and inductance levels are key. These three variables fine all major coil parameters, and they will impact every electrical specification plus all aspects of performance for its entire life – including for a large part – determination of its life.

Plitron’s design tools, Lab Capabilities, Tests, and Measurements

The following assisted design tool and measurement processes are being used, as a means to comply with customer driven specifications. We have not listed standard common industry known testing, such as power or bandwidth. They are listed in no specific sequence and is not intended to indicate are full capabilities.

Design verification as a tool for conducting research in reducing the number iterations to meet the required specifications.

A Computer Aided Engineering (CAE) software package designed to perform full three-dimensional simulations of magnetic physical systems using boundary element method is used. This software tool is used to model the system and have it solved for magneto static condition. The solved model displayed magnetic field distribution in the system, identifying local saturation areas, if existed, calculate flux density inside a volume or across a surface and most other related magnetic parameter.

Measurement and Qualification of Acoustic Noise Emitted by Power Transformers under various line conditions

Tests are conducted under various line conditions, such as normal, high line, and adverse situation such as DC imposed on to the mains. Based on original research, Plitron has created a device, which can superimpose a controlled DC component across the line. While in an anechoic chamber, we can measure transformer noise SPL calibrated to national standards, utilizing our own proprietary monitoring system. The result is that transformer noise can be quantified, and become a guaranteed manufacturing specification. Noise curves can be printed and maintained for reference. The results obtained are subjective in nature, and we can empirically and accurately correlate numerical lab results with real-world performance, and thus set pass-fail criteria, and eliminate transformer noise problems in the field.

Measurement and qualification of temperature rise of transformer under partial and/ or full load conditions.

This test is done by using both embedded thermocouples inside the transformer and on the outside of it and monitoring the temperature rise under load condition until the temperature stability is reached. The rise of resistance method of measuring the temperature rise is also conducted. These methods are required by the regulatory approval bodies, if the transformer is required to be approved by any of the agencies.

Verification of the specifications

Testing is conducted by using an automated tester that performs number of tests over a period of a few seconds. Some of the major parameters that are tested for are continuity, magnetizing current, leakage inductance, active inductance, no-load voltages, hi-pot, and more.
