Manufacturing method of dual-power output energy taking magnetic core

Abstract

The invention belongs to the field of electricity. The invention relates to a magnetic core, in particular to a manufacturing method of a double-power-output energy-taking magnetic core. The manufacturing method of the energy-taking magnetic core is based on the actual situation of engineering application; firstly, the working state of a magnetic core is pre-judged; a calculation process of an inapplicable unsaturated working state in engineering practice is omitted; coefficient simplification calculation is introduced, the influence of process variables such as magnetic core resistance impedance, leakage inductance voltage drop, magnetic core hysteresis loss and eddy current loss in a numerical algorithm and the difference of theoretical calculation and engineering application are compensated through coefficients, a complete output power calculation method is formed, and the method is convenient, simple and convenient to apply. The single energy-taking magnetic core power supply provides two kinds of output power, the application of the energy-taking magnetic core is expanded, the output power of the magnetic core is quantified, the output can be directly applied to a post-stage circuit, a power control circuit does not need to be added, the production cost is reduced, the production efficiency is improved, and the circuit space is saved.
