Abstract: The present invention provides a power limiting circuit for inverter device and an inverter device, which pertains to the technical field of power source inverting. The inverter device comprises a first logic judging circuit for comparing an input current of an inverter circuit with a first preset current threshold and outputting a first signal when said input current is larger than the first preset current threshold; and a shunt circuit for shunting a portion of the input current of the inverter circuit when receiving said first signal; wherein, the shunt circuit comprises a shunt resistance and a first controllable switch, the shunt resistance and the first controllable switch are connected in series and then parallel-connected to input ends of the inverter circuit, a control end of the first controllable switch is connected to an output end of the first logic judging circuit for controlling the first controllable switch to be connected when receiving said first signal.

Abstract: A single-cylinder single-claw double-card punching machine, including an air cylinder; the working end face of the air cylinder is connected to a connecting frame; a gantry moving frame is disposed in the middle of the lower part of the connecting frame in an interleaved manner; a piston rob of the air cylinder passes through the connecting frame to connect with the gantry moving frame; both sides of the connecting frame are provided with snap action moving device; a retaining clamp and a folding clamp are disposed at the bottom of the connecting frame; and a card-pushing sheet and a cutter are disposed under the gantry moving frame. The card punching speed of the single-cylinder single-claw double-card pneumatic punching machine is as high as 166 times per minute, with high efficiency and energy savings.

Abstract: The present disclosure provides a multimedia picture generating method, device and electronic device, wherein the multimedia picture generating method comprises acquiring a picture of a photographed subject of a photographing device; extracting a figure image as a foreground image from the picture after receiving an instruction for removing picture background; performing voice recognition after receiving a voice command inputted by a user; searching out multimedia content that matches a user command information recognized by voice recognition from a multimedia database as background content for the picture; and generating a multimedia picture that contains the foreground image and the background content.
