MEDICAL SUCCESSIVE MAGNETIC PULSE GENERATION DEVICE

摘要

Provided is a smaller, lighter and more power-saving successive magnetic pulse generation device. A discharge circuit (K) comprises, in an annular series connection, a pulse coil (6) for magnetic therapy which generates an eddy current in a subject site (3), a charge/discharge capacitor (4), and a switching semiconductor element (7) which supplies a discharge current from the charge/discharge capacitor (4) to the pulse coil (6). In a step-up transformer (1), a primary coil (1a) is connected to an AC power source (2) and a secondary coil (1b) is connected to an input terminal (5a) of a full-wave rectifier circuit (5). A control unit (8) is connected to the switching semiconductor element (7) and controls the conduction timing of the switching semiconductor element (7). Each output terminal (5b, 5b) of the full-wave rectifier circuit (5) is connected to each terminal (P1, P2) of the charge/discharge capacitor (4). An inductor (9) is connected between the output terminal (5b) of the full-wave rectifier circuit (5) and the terminal (P1) of the charge/discharge capacitor (4).
