Description

Technical Field

[0001] The present application relates to the technical field of inductors, and in particular to an integrated inductor transformer. Background Art

[0002] The transformer uses the principle of series resonance or parallel resonance to generate large current and high voltage. It is generally used for large capacitance or large inductance loads. By using the parallel resonance of the load and the device, a larger load current can be obtained with a smaller excitation current; by using the series resonance of the load and the device, a high voltage can be obtained on the load with a lower excitation voltage. An inductor is a component that can convert electrical energy into magnetic energy and store it. With the rapid development of new energy vehicles and the increase in cruising range, the requirements for charging power, voltage and current of chargers are getting higher and higher. In traditional solutions, increasing output power is generally achieved by connecting multiple transformers and inductors in parallel. When multiple transformers and inductors are used in the charger for parallel output, the charger is larger in size and more complicated in process. Summary of the invention
