Functional Integration

The structural integration of several functional elements into a single functional unit allows for a multi-functional use and/or a reduction of power components / conversion stages and accordingly enables disruptive performance improvements concerning power density, efficiency and realization effort. Following the integration approach PES has demonstrated a new ultra-low EMI quasi-single-stage buck-boost VSD inverter, an isolated front-end solid-state transformer, an ultra-compact three-port PCB-integrated EV DC/DC converter and a record-breaking efficiency (99.1%) matrix-type isolated AC/DC converter for future data centres.

Moreover, a novel single-to-three-phase AC/AC converter utilizing the moment of inertia of the supplied electric motor for power pulsation buffering, a novel self-bearing integrated linear-rotary actuator concept and a self-bearing pump capable of processing phosphorus acid at 250 °C have been patented and/or experimentally verified.
