Where conventional transformers reach their limits<\/h2>\n

<\/p>\n

<\/div>\n

Solid state transformers (SST) become attractive wherever conventional 50\/60 Hz transformers reach their limits \u2013 for instance at high power densities, under dynamic loads or in confined installation space. SST concepts combine power electronics with high-frequency magnetic components and thus open up new degrees of freedom in system design.<\/pee> The magnetic materials largely determine losses, size and thermal behaviour. Blinzinger Elektronik develops ferrite materials designed specifically for the requirements of modern SST topologies.<\/pee> <\/p>\n

Background: how transformer design has evolved<\/h3>\n

As requirements grow through decentralised power generation, electric mobility and DC-based grids, power-electronic voltage conversion is moving further into focus.<\/pee> SST typically operate in the kHz range. This allows transformers to be designed far more compactly \u2013 provided the magnetic materials keep frequencies and losses under control. The choice of ferrite therefore becomes a central design parameter.<\/pee> <\/div>\n

What a solid state transformer is<\/h2>\n

<\/p>\n

<\/div>\n

A solid state transformer is a system consisting of power electronics, control and a high-frequency transformer. Voltage conversion takes place in several stages \u2013 AC\/DC, DC\/DC, DC\/AC. Additional functions such as voltage regulation, reactive power management or galvanic isolation can be integrated.<\/pee> The high-frequency transformer in the DC\/DC stage largely determines efficiency, power density and thermal design. Its properties depend directly on the ferrite material used.<\/pee> <\/div>\n

Innovation in transformer design<\/pee> <\/p>\n

Fast semiconductors put pressure on the magnetics<\/h2>\n

<\/p>\n

<\/div>\n

Semiconductors based on SiC and GaN enable higher switching frequencies and steeper edges. This reduces the size of passive components, but places greater demands on the magnetic components.<\/pee> As frequency rises, core losses typically increase as well. Without suitable ferrites, the efficiency gained from fast semiconductors is quickly offset by thermal problems and additional cooling effort.<\/pee> <\/div>\n
