Beschreibung
Zusammenfassung:	The invention discloses a variable-frequency pulse type X-ray control circuit and a pulse flaw detection device. The frequency conversion pulse type X-ray control circuit comprises a single-chip microcomputer, a synchronous circuit, a power supply circuit, a primary voltage setting circuit, a voltage regulation chopping drive circuit, an inversion chopping drive circuit and a high-voltage drive circuit. The primary voltage setting circuit outputs a set voltage according to the voltage setting signal, and the voltage regulation chopping drive circuit outputs a voltage regulation signal according to the set voltage when receiving the voltage regulation control signal. The synchronization circuit outputs a synchronization pulse signal according to the received synchronization signal, and theinversion chopper drive circuit outputs a preset high-voltage drive signal according to the received inversion control signal. And the high-voltage driving circuit outputs a high-voltage pulse power supply signal to drive the
