| description | The invention discloses a core type permanent magnet transformer which comprises an iron core and a plurality of permanent magnets. The two sides of the iron core are symmetrically lapped with at least one permanent magnet with the same polarity, the iron core is separately sleeved with an input coil and an output coil, an output end circuit formed by the output coil is connected with a load, and the load is connected with a capacitor in parallel. The iron core is formed by stacking cold-rolled non-oriented silicon steel sheets, the cross section of the iron core is rectangular, and the thickness delta of the silicon steel sheets is 0.2-0.5mm. A homopolar magnetizing method is adopted, and on the premise that the same effect is achieved, no permanent magnetic circuit is additionally arranged, and no electronic component for controlling the electromagnetic flux direction is additionally arranged. The total length of the magnetic circuit is reduced, the magnetic resistance is reduced, the iron loss is reduced, |
