Abstract:
1. A high voltage inverter device that receives, as an input voltage, a DC voltage or a voltage composed of a DC component with a pulsating flow superposed thereon, switches the input voltage to pass an exciting current to an excitation winding on a primary side of a transformer, and outputs a high voltage from an output winding on a secondary side of said transformer, wherein said transformer is composed of a plurality of separate transformers having same characteristics, excitation windings of said plurality of transformers are connected in parallel and simultaneously excited, output windings of said plurality of transformers are connected in parallel or in series with one another, and time axes of output voltage waveforms of the output windings are synchronized, and wherein each of said plurality of transformers is a resonant transformer whose output voltage is proportional to a sharpness of resonance Qe.
