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: A voltage source converter has director valve phase legs in parallel with waveshaper phase legs between two DC terminals. The director valve and waveshaper phase legs include upper and lower phase arms alternately operated to form waveshapes on AC terminals of the converter, thereby allowing a number of waveshaper phase arms to be available for use for other purposes. At least one of the available phase arms is controlled to contribute to other aspects of converter operation than waveshaping.
Abstract: A robot has a gripper for gripping parts and releasing the gripped part at a destination position. The gripped part is vibrated at the destination position to cause the gripper to release the gripped part. The gripped part can be directly vibrated or vibrated by vibrating the mechanical structure of the gripper or by vibrating air in the gripper mechanical structure. The vibrator can connect the gripper to the robot. The vibrator can be inside or attached to the one or more of the articulated fingers of the gripper. The vibrations can be stopped when a sensor detects that the gripped part has been released or after the passage of a preset vibration time.

Abstract: A method and a device for supplying energy to a low-voltage load using an electronic power supply device. The method involves: a) setting the power supply device to be able to provide an output current to the low-voltage load up to a specified peak current value upon demand; b) monitoring the output current (IL) provided to the low-voltage load by the electronic power supply device to detect an increase of IL over a threshold (IN) which is lower than the peak current value, c) if an increase of IL to an increased output current value higher than IN is detected, detecting the increased IL value and ascertaining an output current pulse duration (tPulse) based on the increased current value; d) providing IL at the level of the increased current value for the duration of the ascertained tPulse; and e) providing the IL at the level of IN after tPulse has expired.
