Power management

Customized power management solutions

The wire­less power sub-system (inverter–resonant transformer–rectifier) is usual­ly inte­gra­ted in a power manage­ment sys­tem (PMS). Within such a sys­tem, a power sup­ply unit ensu­res safe iso­la­ti­on from the mains and inclu­des a cir­cuit for power fac­tor cor­rec­tion (PFC), if necessa­ry. One or more DC/DC con­ver­ters gene­ra­te the ope­ra­ting vol­ta­ges requi­red by the app­li­ca­ti­on. A bat­te­ry and a bat­te­ry manage­ment sys­tem (BMS) are also requi­red in many cases.

This are some tasks in which eta­tro­nix noti­ce­ab­ly eases its cus­to­mers’ bur­den by taking over respon­si­bi­li­ty from con­cept deve­lo­p­ment through to seri­es pro­duc­tion. Our pro­ject expe­ri­ence, effi­ci­ent pro­ces­ses, and in-depth know­ledge of the spe­ci­fic requi­re­ments of indus­tri­al sec­tors such as medi­cal tech­no­lo­gy, indus­tri­al auto­ma­ti­on and mea­su­re­ment tech­no­lo­gy enab­le us to safe­ly deli­ver projects.

Power conversion

eta­tro­nix deve­lo­ps and manu­fac­tures AC/DC and DC/DC con­ver­ters, power fac­tor cor­rec­tion sta­ges (PFC), and bat­te­ry char­ge regu­la­tors wit­hin a power ran­ge of bet­ween 50mW and rough­ly 10kW. We rely on tried and tes­ted plat­form solu­ti­ons when deve­lo­ping application-specific solu­ti­ons. Depending on the spe­ci­fic requi­re­ments, and giving due con­si­de­ra­ti­on to value engi­nee­ring, we also employ the latest topo­lo­gies and tech­no­lo­gies. These inclu­de SiC and GaN semi­con­duc­tor com­pon­ents, as well as digi­tal con­trol and regu­la­ti­on of power modules.

Battery management

The eta­tro­nix bat­te­ry manage­ment sys­tem is sui­ta­ble for almost every cell che­mi­stry and cell con­fi­gu­ra­ti­on.  Charging capa­ci­ties typi­cal­ly ran­ging from 2.5W to 1kW, char­ge and bat­te­ry sta­tus moni­to­ring, exten­si­ve safe­ty func­tions, and a mul­ti­tu­de of inter­faces, make it par­ti­cu­lar­ly well sui­ted for use in por­ta­ble mea­su­ring devices, in dro­nes and in auto­ma­tic gui­ded vehi­cles (AGV).


Virtually all modern devices and sys­tems requi­re inter­faces and bus sys­tems in order to exchan­ge data, eit­her intern­al­ly, i.e. bet­ween the dif­fe­rent modu­les of a device, or with exter­nal inter­faces to enab­le inte­gra­ti­on in net­works. Sensor net­works and fiel­dbu­ses have beco­me indis­pensable in auto­ma­ti­on, espe­cial­ly in Industry 4.0 with its incre­a­singly auto­no­mous robo­tics and vehi­cle tech­no­lo­gy. eta­tro­nix has veri­fied hard­ware and soft­ware stacks for almost all com­mon inter­faces and bus sys­tems, such as USB, USB‑C, CAN, CANopen, SMBus, PMBus, I2C, RS232, RS485, Ethernet, WiFi and Bluetooth.
