03/2018 Optimize Your SMPS with MPS

We Know High-Power Conversion Efficiency

High-power conversion efficiency is important in your SMPS design, especially in your DC-DC switching converters.

MPS Industries, Inc. is a supplier of magnetics for SMPS. We will work with you to select and design the most optimized components for your needs. This includes various transformer topologies, output filter inductors and chokes.

Our magnetics can be used in various non-isolated topologies, such as buck, boost, charge pump as well as isolated topologies such as flyback, forward, resonant, full and half bridge.

An Inductor Example for High-Frequency SMPS

In high-frequency SMPS, you may consider using an inductor made of powdered iron or ferrite, such as our P11T80B (imaged above). Powder core has higher core loss with soft saturation, while ferrite saturated more sharply but has improved core loss

A Recipe for Success: MPS on SMPS

With our skilled team, you don't have to worry about big losses in power or size reduction. Upon request, we can provide the loss data for you to determine the estimated efficiency of your SMPS. We look forward to helping you achieve the highest performance level on the market today!

12/2017 Custom Inductor Solutions

MPS' HEW High Current Inductors are the most comprehensive on the market today!

Options range from our standard smaller surface mount 30A inductors (HWIA2918S series) to larger customized chassis-mounted inductors, capable of handling up to 1000A.

Our HEW inductors have less skin effect at high current for high frequency applications, as well as low EMI due to the clean simple winding, lower inter-winding capacitance and less capacitive losses (compared to multi-strand round wires).

Depending on your requirements, MPS might offer traditional round wire for consideration. If designing for a resonance application, MPS can design using high-strand count litz wire molded to MW-79C (3000V) too.

Think Big: 100A-1000A Inductor Capabilities & Customization Single or 3-Phase, Coupled Inductors for your design:

  • Potted with thermally conductive material for mounting to cold plate/heat sink or open type for convection/forced air cooling
  • Customized mounting and connections for hassle-free integration into customer system
  • Traditional type round wire and copper foil design
  • Can design to handle capacity up to 1000A

Using modular design, our inductors can be connected in parallel for increased current capacity or in series for increased inductance!

About MPS Industries, Inc.

MPS makes the most dense, compact, and versatile range of HEW inductors to meet your electrical and mechanical needs. Our engineers work closely with you to create your design based on your electrical and mechanical requirements for your specifications.

With regards to performance, the coupling factor (K) of the magnetic epoxy inductors falls somewhere between that of ferrite shielded and unshielded inductors. These new inductors are offered with the same or similar overall dimensions and footprint as their ferrite shielded and unshielded counterparts and so provide a nice alternative, bridging the gap between the two.

Ideal applications for these lower cost inductors include DC/DC converter, computer, LED lighting, and various industrial and consumer electronics products.

LLC Resonant Transformer

Half Bridge LLC Resonant Transformers

Gardena, CA (October 1st 2013) - In today's energy conscious environment, electronic product manufacturers are focused on efficiency, as they are faced with the difficult task of continuously improving performance while consuming less power. To assist our customers with their energy conservation efforts, MPS Industries introduces two new LLC Resonant transformers (P6503 and P6504) that are designed to provide very high efficiency and very low power loss.

These transformers are ideal for use in conjunction with an upstream PFC circuit in applications that require maximum efficiency, such as the LLC resonant converter. The LLC resonant topology allows for zero voltage switching (ZVS), resulting in drastically reduced switching losses and significantly improved efficiency. MPS Industries' new half bridge LLC resonant transformers are ideally suited for such applications, and our team of highly experienced engineers are also ready to work with our customers to design custom solutions to meet individual needs.
