OwnTech's TWIST reprogrammable power converter is a bi-directional 300W power converter. It features a dual 12V to 72V low side and a single 10V to 100V high side. Its maximum current value is 8A per power channel. The power channels can be used independently, yielding two output voltages or combined to double the current.
A reasonable power rating is 300W. The converter is meant to operate at 200kHz with interleaving control.
The TWIST converter 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 TWIST Reprogrammable power converter 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.
