MOLDED POWDER INDUCTORS: NINE NEW PLATFORMS FOR AUTOMOTIVE AND COMMERCIAL APPLICATIONS

Pulse Electronics is excited to introduce a total of nine new series’ of automotive and commercial grade molded powder inductors.  The PA540x, PA544x (commercial grade) and PM540x, PM544x (automotive grade) range in size from 3.7×3.4×1.2mm up to 14×12.8×3.5mm. These platforms add to Pulse’s already popular line of high efficiency power inductors. They are ideal for high current, non-isolated…

Double Your Power Density, Optimized DC/DC Transformers

  Pulse Electronics continues to innovate and bring to market exciting new power magnetic products.   Leveraging the research presented in our 2019 APEC paper “Power Transformer Core Optimization Enables Dramatically Increased Power Density” Pulse has released an improved DC/DC transformer series that maintains the industry standard footprint but doubles the component power density to over 11W/cm3.   The…

Current sense magnetics

How Does it Work?

In many power supplies and circuits it is advantageous and even necessary to monitor the currents flowing in, out, or through a power supply circuit. For example, monitoring for transient overcurrent conditions in the output a DC-DC converter to trigger protection circuitry or to monitor the resonant tank current for control of a Resonant LLC…

COMPACT, SAFETY COMPLIANT, CURRENT SENSE TRANSFORMERS

Compact, Safety Compliant, Current Sense Transformers

  Pulse expands its range of surface mount current sense transformers with the introduction of its first safety standard compliant products with high isolation and enhanced insulation. Using the Pulse patented sidecar construction developed for our high isolation transformer series, the PH9500 series utilizes this unique packaging style to offer basic insulation with 8.2mm creepage…

Isolation transformer

Low Power Isolation Transformers

With the proliferation of high voltage battery packs in automotive and energy storage applications the demand for compact,  high isolation voltage transformers is growing exponentially. These devices, traditionally used to isolate signals between low voltage and high voltage circuits and provide voltage to gate drive and IGBT circuits, are now one of the critical devices…
