Abstract

The invention relates to an X-ray machine power supply device with the energy compensation function. The X-ray machine power supply device comprises a filtering module, a rectifying module, a high-frequency inverter module and a high-frequency power transformer, wherein the filtering module, the rectifying module, the high-frequency inverter module and the high-frequency power transformer are sequentially and electrically connected. The X-ray machine power supply device further comprises a storage battery set, a first selective switch, a second selective switch and a filtering energy-storage capacitor C1. The two output ends of the rectifying module are electrical connected with the two input ends of the high-frequency inverter module respectively through the first selective switch and the second selective switch. The two ends of the filtering energy-storage capacitor C1 are electrically connected with the two input ends of the high-frequency inverter module respectively. Through switchover of the selective switches, two working modes of storage battery set power supply and electric supply power supply are achieved, due to the fact that the two ends of the high-frequency inverter module are electrically connected with the filtering energy-storage capacitor C1, the requirements of the storage battery set are lowered, the requirements for electric supply power source quality and input power are lowered, an X-ray machine can stably work under the severe electric supply condition, and the indoor and outdoor application range of the X-ray machine is widened.

Description

technical field [0001] The invention relates to a power supply device, in particular to an X-ray machine power supply device with energy compensation. Background technique [0002] The basic components of an X-ray machine are a high-voltage generator, an X-ray tube assembly, an auxiliary frame and an image receiving device. Among them, most manufacturers have used high-frequency inverter technology as the high-voltage generator device that is the energy source for X-ray machines to generate X-rays. The working principle is: 50Hz input network power becomes DC power after filtering and rectifying. Or use batteries to supply power and get direct current power directly. After the DC power is filtered by a large-capacity capacitor, it is input to the frequency inverter module to convert the DC power into a high-frequency AC power above 20kHz, and finally sent to the high-frequency power transformer module to generate a high voltage above 40kV. The high voltage is applied to t...

Problems solved by technology

[0004] Disadvantages of the existing technology: 1) The output power of the high-voltage generator depends on the quality of the mains power supply, and a rechargeable battery must be used as a compensation power supply in harsh environments; 2) The filter circuit uses an electrolytic capacitor with a capacity of mF, which has a small capacity
