The 3L MCU and Sensor Card one of three boards that form the control stack of the Inverter. The board comprises various linear and switching power supplies, isolated (5 kV) high voltage 3 phase AC and DC measurement interfaces, high current sensor and temperature measurement interfaces, signal conditioning circuitry, discrete digital logic safety circuitry, and external interfaces for earth fault measurements.
Electron Artz was tasked to evaluated and redesign the schematics from ground up to incorporate all required functionality, ensure high analogue signal integrity, ensure all subsystems were properly designed. The first design worked as expected and passed certification without the need for further revisions.
Ario MetaPower approached Electron Artz for design assistance with the electronic hardware for their 200kW inverter. Electron Artz was tasked to review, redesign and include additional functionality into two of the three boards of the inverter control stack. We were also tasked to design two new boards for the inverter from ground up.
The 3L MCU and Sensor Card was one of the two boards that were reviewed & redesigned.
