- The KM3 converter is a Maximum Power Point Tracking (MPPT) converter for thermoelectric power generating arrays (TEGs).
- Battery charging management improves the state of charge of the output battery and can be deactivated by jumper selection.
Battery charging management improves the state of charge of the output battery and can be deactivated by jumper selection. 12V and 24V batteries are currently supported and 48V batteries will be supported from the beginning of 2018.The proprietary MPPT algorithm tracks fast thermal transients and recognises steady states to
increase the thermal-to-electrical efficiency of the system. The KM3 converter interfaces TEGs whose
voltage can be either lower or higher than that of the output battery. It starts its voltage step-up
operation with input voltages as low as 2V and continues harvesting electrical power provided that
the TEG open-circuit voltage does not exceed 85V. The KM3 converter uses synchronous rectification
to operate in Boost, Buck-Boost or Buck modes. Its innovative construction design minimises heat
dissipation and EMI and allows extremely high power densities.
