The development of voltage generator

High frequency and high voltage generator is an important part of X-ray equipment.It is a flexible, highly stable power source connected to X-ray tubes, image intensifiers and computers.The image processing system together constitutes a complete closed loop medical imaging system, which consists of four parts: high frequency and high voltage generator, rotating anode power supply, X-ray tube filament power supply and microprocessor system.

Due to the microprocessor control, the fault detection of high frequency and high voltage generator has strong intelligence.According to the display error code and the function board LED, the fault source can be accurately located and the fault can be eliminated in time.Because of microprocessor control, the fault detection of high frequency and high voltage generator has high intelligence.According to the display error code and the function board LED, the fault source can be accurately located and the fault can be eliminated in time.

The high voltage generation and control of the high frequency X-ray machine are accomplished by the high frequency high voltage generator, namely the ALTERNATING current inverter, which can become a fixed frequency variable high voltage.Hf hV generators usually use preset control signals to control the generation of hV.The basic principle of the hf hv generator is an ac inverter, which can convert the supply voltage to a high voltage signal with a frequency of 20kHz or higher through pulse width modulation.The signal is sent to the high voltage transformer, and the primary voltage is changed to 40-150 kv (fluctuation is usually 2%) through the transformer circuit and rectifier circuit.At the same time, the dynamic signals in the tube are collected accurately, and the high frequency high voltage generator is controlled to control the X-ray high voltage.
