The invention discloses a control system and method for a torpedo ladle cover adding and taking device, equipment and a medium, and belongs to the technical field of metallurgy. The control system comprises a battery pack, a high-frequency power module, an inverter, a cover adding and taking device and a controller, the cover adding and taking device comprises a tank cover, and the tank cover is used for covering a tank opening of the torpedo tank; the battery pack, the high-frequency power module, the inverter and the cover adding and taking device are sequentially connected, and the high-frequency power module is connected with the controller. The high-frequency power supply module is used for adjusting the output voltage of the battery pack to a preset target direct-current voltage and outputting the voltage to the inverter or the controller; the inverter is used for converting the target direct-current voltage output by the high-frequency power supply module into a preset target alternating-current voltage and outputting the preset target alternating-current voltage to the cover adding and taking device; the controller is used for controlling the cover adding and taking device to conduct cover adding and taking operation. When the torpedo ladle is located at any position, the control system has driving force to carry out cover adding and cover taking operation.

This utility model discloses a power supply circuit, belonging to the field of electric vehicle instrument technology, specifically relating to a power supply circuit for an electric vehicle instrument, including: a switching regulator U1, an input filter component, an output filter component, a voltage divider network component, and a Zener diode D1; this utility model adds a constant voltage circuit to the power supply circuit, which stably converts a wide input voltage range into DC output, while the input filter component filters out noise from the input power line and reduces the backflow of high-frequency current ripple generated during the operation of the switching regulator. The output filter component smooths the high-frequency pulsating current generated by the switching action into a relatively stable DC voltage and further filters out high-frequency noise. In addition, the voltage divider network component samples the voltage and feeds it back to the switching regulator U1 to adjust the output voltage to ensure that it is maintained at a set constant value, thereby achieving stable output voltage.
