Description

Technical Field

[0001] The present application relates to the technical field of high-voltage generator power supply control, and in particular to a power supply control system for a high-voltage generator and a medical vehicle using the power supply control system. Background Art

[0002] In medical imaging equipment, the high-voltage generator is one of its core components. Under program control, the high-voltage generator is primarily used to generate a stable, high-frequency, inverted DC high voltage with sufficient power to supply the X-ray generator, which generates detection radiation for medical imaging. Current high-voltage generators generally require a 380V AC power supply. To meet the varying power requirements of the X-ray generator during operation, the generator requires a high-voltage inverter to adjust the control voltage parameters. Furthermore, for safety reasons, the high-voltage generator is typically equipped with a high-voltage detection circuit to verify that the input power source meets the generator's AC voltage, such as 380V AC. If the input power voltage fails to meet the detection standard, the generator will not start.

[0003] Existing technology typically uses direct power from an external AC power source. However, in certain specialized applications, such as medical carts equipped with CT scans and other medical imaging equipment, power supply stability and reliability cannot be guaranteed. Finding a 380V power source during outpatient medical examinations can be difficult, seriously impacting the smooth progress of the examination. While battery energy storage systems can replace the 380V rectifier voltage, the high-voltage generator's 380V detection circuit still won't function properly. While battery voltage inversion can meet this requirement, it's costly and requires a custom inverter.

[0004] Therefore, there is an urgent need for a power supply control system solution that can use ordinary power instead of 380V power to facilitate the power needs of medical vehicles when they are out. Utility Model Content

The power supply control system includes:

[0007] An energy storage battery, the energy storage battery outputs a DC voltage, and the output end of the energy storage battery is electrically connected to the input end of the high-voltage inverter;

[0008] The transformer circuit includes a primary winding and a first secondary winding, a second secondary winding and a third secondary winding. The primary winding is electrically connected to an external AC power supply. The first secondary winding, the second secondary winding and the third secondary winding have the same winding direction. The tail end of the first secondary winding, the head end of the second secondary winding and the tail end of the third secondary winding are connected and grounded. The head end of the first secondary winding, the tail end of the second secondary winding and the head end of the third secondary winding are respectively connected to the three input ends of the high-voltage detection circuit.
