The H-bridge circuit in this Technical Note is a full bridge DC-to-DC converter allowing operation of a brushed DC motor (48 V max, 12 V min, 5 A max). All electronic functions are designed with Nexperia discrete and logic IC components (low cost, no microcontroller or software needed). Read more >>
AC EV wallbox / Bidirectional DC wallbox
Car electrification is well underway and numerous countries have ambitious plans to rule out new petrol and diesel in the near future. One of the critical challenges in making electric vehicles more common, is the availability of accessible charging points. Single phase 3.7-11 kW and 3-phase 11-200 kW wall or pole-mounted AC boxes are currently the standard option. But bidirectional technology (allowing electricity to flow into and out of EVs) is rapidly maturing with 7.4-22 kW bidirectional DC Wallboxes. This will enable cars to become mobile storage platforms and fully integrated into smart grid infrastructures.
