3DPower™ FULL BRIDGE LLC TRANSFORMER + RESONANT CHOKE——A greener, space and cost saving solution for power electronics

时间： 2020-06-29 来源：PREMO

技术问答

Main challenge today in power electronics (industrial, HV & EV) is to manage more and more high power (OBC/DCDC converters) in the smallest possible space, without compromising system reliability. PREMO 3DPower™ is a revolutionary concept in power magnetics integration, were existing magnetics within conventional HEV On-Board Chargers and DCDC converters are merged into one single and compact product.

3DPower™ is the first product to integrate two magnetics components that share the same core and feature two orthogonal magnetic fields at all points within the core. Maximum power density is achieved by reducing the size and increasing the power dissipation with the latest high thermal conductive materials.

KEY ADVANTAGES

50% SIZE AND WEIGHT REDUCTION

2 Components in 1

50W/CM3 POWER DENSITY

Maximum power density is achieved by reducing the size and increasing the power dissipation with the latest high thermal conductive materials (CoolMag™)

X2 LESS FERRITE USE

Combining 2 magnetics components in one special single core

CUSTOMIZATION

3DPower™ solution can be fully customized to meet customer requirements. There are almost infinite possibilities of configurations of core size, core material, airgaps, core shapes:

> For topologies as full bridge LLC resonant, boost converter, full bridge phase shifted, etc…

>For a given Power, voltage and current, and switching conditions (frequency and duty cycle)

>For a given set of thermal constraints
