HEW_™ Single Phase AC/DC Reactors: A Recommended Alternative

MPS Industries, Inc. introduces our HEW (Helical Edge Wound) Single Phase AC/DC Reactors, customized and optimized for your specific reactor needs. These reactors are a recommended alternative for amorphous/lamination core and copper foil wound reactors.

Highlights and Advantages to this Alternate Design Approach:

• Designed with distributed gap powder cores = minimum gap loss
• No concentrated hot spot on the winding due to fringing flux from the gap
• Soft saturation
• Low audible noise level

• Clean single layer HEW winding
• Single layer winding = better heat dissipation
• Machine-wound = less labor intensive, more cost effective
• Lower losses (for AC), proximity effect, and capacitance vs. copper foil counterpart

Surface Mount High Current HEW Inductors

Gardena, CA (July 1st 2016) – MPS Industries’ HWIA2918S Series offers a High Current HEW Inductor in a surface mount, low-profile, compact form.

Maximum height for these inductors is 18mm and the package includes a dummy 3rd pin for extra mounting stability. The HWIA2918S series is constructed using wire with true 30 Amp handling capacity.

The standard series inductance ranges from 3.3 microhenries up to 33 microhenries and very low DCR.

Gardena, CA (May 1st 2016) – MPS Industries’  HWI4427 and HWI4434 series of Helical Edge Wound (HEW) inductors is the lowest profile and highest current density package size in the industry, making them perfect for very high density 1U power supplies above 2kW.

These inductors are available with height as low as 27mm and in a variety of mounting options, including horizontal, vertical, and with additional mounting hardware for added support. The HEW flat wire coil minimizes losses at high frequencies and can handle up to 160 Amps per inductor (with cooling) and can be paralleled to meet 300 Amp requirements.  

Using different materials available, MPS is able to configure the inductors for various magnetic applications such as PFC, DC output, AC input, or Boost in the same low profile package. We offer a wide variety of standard High Current Inductors with ability to customize per client specifications as well.  

Applications include:

• Very high power density rack mount or benchtop 1U power supplies
• Electric Car (EV) applications
• EV Wireless Charging
• High Power PV Micro-Inverters above 1kW

Gardena, CA (March 1st 2015) – MPS Industries, Inc. continues to add to our growing line of Flat Wire High Current Inductors. Our new HWI4427 and HWI4434 Series range from 5 microhenries to 91 microhenries and rated current up to 51 amps.

These inductors provide high current handling capacity in a compact package with superior thermal management and heat dissipation. Both series offer a variety of mounting configurations including vertical, horizontal, thru-hole, surface mount, and more. A full range of custom designs is also available upon request.

Gardena, CA (November 1st 2014) – MPS Industries introduces a new series of High Current Planar Transformers using our flat wire, helical winding construction. The planar design yields high efficiencies in a compact, low profile package size. Additionally, by incorporating the flat wire, helical wound coils, we are able to offer a wide selection of custom configurations with considerably shorter design lead times and lower startup and production costs than traditional planar designs. The coil structure also allows for excellent heat dissipation and high current handling capacity.

Our HP30 Series consists of Full Bridge Transformers with rated power from 500W to 1000W. A full range of custom designs is also available upon request.

Gardena, CA (July 1st 2014) – MPS Industries is releasing a line of flat wire, high current inductor modules for inverter systems. The new H1300 Series and HWI57A2 Series inductors are ideal for use in PV Inverter, String Inverter, and Bidirectional Inverter applications.

The flat wire coil construction offers superior thermal management and heat dissipation, which results in superior performance and reliability. The inductor modules are also potted in aluminum enclosures with thermally conductive potting material to further enhance thermal management, prevent vibration issues, and allow for easy mounting.

The H1300 Series features current rating over 100 Amps and the HWI57A2 Series features current rating over 200 Amps. Custom design is available up to 500 Amp current for inverter systems 20kW and up. Click here for full press release.

Gardena, CA (March 1st 2014) – MPS Industries introduces a new line of surface mount power inductors featuring magnetic epoxy shielding as a lower cost alternative to conventional ferrite shielded inductors. By replacing the traditional ferrite shield with a magnetic epoxy resin, we are able to significantly reduce both material and labor costs, as well as improve production lead times.

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.

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.
