<p>PROBLEM TO BE SOLVED: To make an electric power unit compact while enabling the electric power unit to output a plurality of high voltages.SOLUTION: An electric power unit includes one drive circuit 16 which supplies electric power to a primary winding 17, output parts 18, 19, and 20 comprising magnetic cores 21, 24, and 27, secondary windings 22, 25, and 28, and control windings 23, 26, and 29, and control parts 30, 31, and 32 which control the control windings 23, 26, and 29. The drive circuit 16 supplies a constant voltage to the primary winding 17, and the control parts 30, 31, and 32 switch the control windings 23, 26, and 29 between a short-circuit state and an open-circuit state to adjust voltages of the output parts 18, 19, and 20; and the primary winding 17 is arranged at one of three magnetic legs that the magnetic cores 21, 24, and 27 arranged in aθshape have, the secondary windings 22, 25, and 28 and the control windings 23, 26, and 29 are arranged at one of the remaining magnetic legs, and a magnetic gap provided at the remaining magnetic leg determines the degree of coupling between the primary winding 17 and the secondary windings 22, 25, and 28.</p> |
