OWNVERTER

OWNVERTER - Three-phase reprogrammable Inverter

OwnTech's OWNVERTER reprogrammable power inverter is a bi-directional 1kW three-phase inverter. It features a 12V to 72V low side and a single 10V to 100V high side. Its maximum current value is 13A per power channel.

It is compatible with multiple types of speed sensors such as sin-cos and hall.

A reasonable power rating is 1kW. The OwnVerter is meant to operate at 200kHz.

The OWNVERTER inverter is fully open-source, with a strong compatibility with the Zephyr RTOS and modular programming approach. A MATLAB® suit for code generation is also available for auto-generating the code.

OwnTech's OWNVERTER Reprogrammable inverter has a dedicated SPIN control board composed of a STM32G474RE microcontroller connected to power drivers and a series of peripherals. This board is electrically isolated from the power side.
