This paper is concerned with High Frequency, High Voltage Generator for X-ray using zerovoltage soft-switching PWM DC-DC power converter by resonant method, which makes the most of the parastic IBC parameters of high-voltage transformer link, for diagonostic X-ray power generator.
The converter circuit basically utilizes phase-shift pulse width modulated series resonant full-bridge PWM DC-DC high-power converter operating at a constant frequency;25kHz.
The high-frequency switching operation of the inverter has some effective advantages with consist in the physical reduction in size and weight and lowered acoustic noise.
The converter output regulation is digitally controlled using DSP(Digital Signal Processor) for obtaining a fast rising time and adjust output voltage within a wide load range.
This converter characteristics are evaluated in terms of computer-aided analytical and experimental results.
