    Abstract: A correction-term adder 1 compares a maximum value max(V*) with an absolute value of a minimum value min(V*). The correction-term adder 1 selects a signal 1−max(V*) when the maximum value max(V*) is larger than the absolute value of the minimum value min(V*), on the other hand, selects a signal −1−min(V*) when the absolute value of the minimum value min(V*) is larger than the maximum value max(V*). Thereby, a signal of correction amount α is calculated. Moreover, the correction-term adder 1 produces a triangular-wave-shaped signal k(max(V*)+min(V*)) by multiplying a gain k by an addition signal max(V*)+min(V*) of the maximum value max(V*) and the minimum value min(V*). This triangular-wave-shaped signal k(max(V*)+min(V*)) is synchronized with the correction amount α. The correction-term adder 1 produces a correction amount β by selecting smaller one in absolute value between the triangular-wave-shaped signal k(max(V*)+min(V*)) and the correction amount α, and adds the correction amount β to the voltage command values V*U, V*V, V*W.

    Abstract: The present techniques include methods and systems for operating an inverter to maintain a lifespan of the inverter. In some embodiments, the switching frequency and/or the output current of the inverter may be changed such that stress may be reduced on the inverter bond wires of the inverter. More specifically, embodiments involve calculating the aging parameters for certain operating conditions of the inverter and determining whether the operating conditions result in aging the inverter to a point which reduces the inverter lifespan below a desired lifespan. If the operating conditions reduce the inverter lifespan below the desired lifespan, the switching frequency may be reduced to a lower or minimum switching frequency of the inverter and/or the output current of the inverter may be reduced to a maximum output current at the minimum switching frequency.

    Abstract: A Multi-Tile Power Management Integrated Circuit (MTPMIC) includes tiles including an MCU/ADC tile and a power manager tile. The power manager tile includes a set of Configurable Switching Power Supply Pulse Width Modulator (CSPSPWM) components. These components, in combination with other circuitry external to the integrated circuit, are configurable to form a selected one of a number of different switching power supply circuits. Upon power up, an internal regulator supplies power to the CSPSPWM. The CSPSPWM then controls the power supply to begin switching in a low frequency start-up mode. The CSPSPWM determines during start-up the current sensing method based on circuitry external to the integrated circuit. A supply voltage generated is then supplied via a conductor of a standardized bus to a processor in the MCU/ADC tile. The processor begins executing instructions, and as a result writes across the standardized bus to configure the various tiles of the MTPMIC.

    Abstract: A controller 40 performs a control operation in a cycle based on a carrier frequency fc of a carrier, specifically, at timings corresponding to the peaks and troughs of the carrier signal. Moreover, in the case where the carrier frequency fc is switched, a disturbance estimation part forming the controller 40 updates control constants that are used for disturbance estimation and are dependent on the control operation cycle, in a control operation performed one cycle after a control operation immediately after the switching of the carrier frequency fc.
