Abstract

PURPOSE:To improve efficiency and simplify a device, by adding high-tension DC voltage to the output of a voltage controlling circuit, and by taking the added output out of an output circuit. CONSTITUTION:A voltage controller is composed of a rectangular wave pulse f0, a gate G, a comparator COP, a transistor Q, a transformer PT, a rectifier circuit RE, and the like, and current is fed to a load RL. Besides, by an error amplifier A1, reference voltage Er and the partial voltage betaE0 of output voltage E0 are compared with each other; its difference component as output voltage V1 is added to the comparator COP, compared with set voltage EC, and added to DC high voltage V2 obtained from a capacitor C1. In this case, when the output voltage E0 is low, then directly from a power source, the output can be stably controlled. Besides, when the output voltage E0 is set to be high, then by working the converter of a switching circuit automatically, the output voltage E0 can be controlled continuously and efficiently from low tension to high tension.
