Abstract: Unique systems, methods, techniques and apparatuses of an active neutral point clamped converter (ANPC converter). One exemplary embodiment is a power conversion system comprising a grid-side converter, a DC link, a multi-phase ANPC converter coupled to an electric machine, and an electronic control system. The electronic control system is structured to selectably operate in a first mode and a second mode in response to a device failure state of the ANPC converter, the first mode operating the grid-side converter to provide a first DC link voltage and operating the ANPC converter using a first modulation index, and the second mode operating the grid-side converter to provide a second DC link voltage greater than the first DC link voltage and operating the ANPC converter using a second modulation index lower than the first modulation index.

Abstract: An apparatus for controlling a robot includes a programmable logic controller (PLC) configured to define, based on a finite state machine (FSM): states and associated operations of the robot, and switching conditions among the states, wherein the robot is switched among different states in response to a switching condition being satisfied. The FSM at least includes an initial state for a self-test procedure to check whether components of the robot are able to operate properly, and a calibration state for calibrating the robot. And a method for controlling a robot. The use of PLC programming language facilitates an easy programming and maintenance of the whole robot system.

Abstract: Methods, systems, and computer readable media for managing the distribution of photovoltaic power in a multi-floor building are disclosed. According to one aspect, a method includes determining power requirements for each of a plurality of loads associated with a respective plurality of floors in a multi-floor building, wherein each of the plurality of floors includes a direct current (DC) distribution bus. The method further includes using a PV converter to supply a power output from a PV source to one or more of the plurality of loads via one or more respective DC distribution buses, wherein the power output is supplied to the one or more of the plurality of loads in an order such that each subsequent load is supplied at least a remaining portion of the power output after the power requirements of a previously supplied load is fully satisfied.
