Modified Multi-Level Converter, M2LeC. M2LeC is a form of Multi-level Converter that combines the functions of generating electric motor wave-forms, with battery charging and management in a single set of power electronics hardware, where the various functions are performed through software alone.

A Multi-Level Converter (MLC) is a method of generating high voltage wave-forms from lower voltage components. MLC origins go back over a hundred years, when in the 1880s, the advantages of DC long-distance transmission became evident.

High Voltage DC Converters HVDC, typical use series connected switched capacitors blocks. The blocks are switched in or out of the circuit to form the desired waveform, typically three phase AC []. More recently in 1999, Tolbert described the use of MLC for battery operated electric motors. Habib's 2018 review paper reviews Multi-Level Inverters (a synonym for MLC) stating the advantages of bi-directional energy flows to power the motor or charge the battery system.
