A RESPONSIVE TEACH INTERFACE FOR PROGRAMMING AN INDUSTRIAL ROBOT
A method of generating a program (C) for controlling an industrial robot, comprising: receiving a tentative control point (P1, P2, P3, P4, P5) to be executed by a manipulator of the industrial robot, wherein the tentative control point is entered using a handheld or body-worn input device (220) with a motion tracking capability; generating a tentative path segment (S12, S23, S34, S45) connecting the tentative control point with a preceding control point; evaluating the tentative path segment's feasibility using a predefined computer model (M) of the manipulator; and providing feedback indicating an outcome of the evaluation.

Embodiments of present disclosure relate to a bidirectional bridgeless PFC circuit. The bidirectional bridgeless PFC circuit comprises a main circuit comprising an input inductor and configured to receive an AC voltage from an AC power supply at a first terminal of the input inductor and convert the AC voltage to a DC voltage, wherein a direction of a current flowing through the input inductor during a positive half of the AC voltage is different from a direction of the current flowing through the input inductor during a negative half of the AC voltage; a current detection circuit electrically coupled to the input inductor and configured to generate a detection signal indicating an amount of the current flowing through the input inductor only during a discharge phase of the input inductor; and a controller electrically coupled to the main circuit and the current detection circuit and configured to generate a zero-crossing signal based on the detection signal. With these embodiments, the direction of the current in the bidirectional PFC circuit can be detected with only one current detection circuit, and the zero-crossing point of the current can be easily determined. Therefore, the power consumption, the size and the control complexity of the PFC circuit can be maintained at a low level.
