Abstract：There is a contradiction of traditional mining intrinsic safety switching converter between large inductance, capacitance which is required by the electrical characteristics (such as big output power, low output voltage ripple, high efficiency) and small inductance, capacitance which is required by the intrinsic safety characteristics. So, this paper introduces magnetic integration theory to the intrinsic safety switching converter to solve the problem and proposes the concept of equivalent electrical inductance and equivalent intrinsic safety inductance. The switching converter can satisfy both the electrical characteristics and the intrinsic safety characteristics by increasing the equivalent electrical inductance and reducing the equivalent intrinsic safety inductance. Take the three-phase interleaving magnetic integrated Boost converter as an example, by analysis of the inner-intrinsic safety characteristics of the converter, the inner-intrinsic safety criterion of the converter is obtained. Comparing with the conventional single-channel Boost converter and the three-phase interleaved Boost converter, it concludes that the three-phase interleaving magnetic integrated Boost converter improve the electrical characteristics and the intrinsic safety characteristics effectively. Finally, the theory is verified with experimental results.
