PURPOSE:To reduce the ripple component of a voltage waveform of a high voltage generator by connecting a plurality of unit converters, operating them in the same frequency and dividing the phase, thereby displacing the phases and driving with each other. CONSTITUTION:A plurality of voltage resonance type converters 2 are connected in parallel between the output terminals of a power source 1. The converters 2 connected a condenser 4 between the input terminals 3a and 3b, and connects the collector of a switching element made of a transistor at the terminal 3a of anode side. The switching element 5 of the converter 2 is operated in ON or OFF at substantially constant frequency, the drive pulses inputted to the respective elements 5 are displaced in the prescribed phase, thereby superposing them from each other. In this manner, continuous output wave can be obtained even without using a smoothing circuit of particularly large electrostatic capacity in the secondary side circuit of the converter 2. |
