Abstract

The invention discloses a transformer structure with effects of bearing large current and dissipating heat. The transformer structure includes a circuit board, a current bearing plate, a transformer core, two wire windings and two plate windings. A rectifying and filtering circuit is disposed on the circuit board and includes at least a filtering inductor, a filtering capacitor and a rectifying switch. The filtering inductor is composed of a deflector on the circuit board and an inductor core placed on the deflector. The current bearing plate is stacked on the circuit board and is electricallyconnected to the rectifying and filtering circuit. The transformer core is disposed on the circuit board. The two plate windings are made of electrode plate materials. At least one round of iron coreis wound around the transformer and fixed on the circuit board. The plate windings are electrically connected to the deflector and the current bearing plate to jointly bear the current flowing through the transformer structure.

Description

technical field [0001] TECHNICAL FIELD The present invention relates to a transformer structure, in particular to a transformer structure with high power density, capable of withstanding large current and effectively dissipating heat. Background technique [0002] There are many transformer structures pursuing higher power density and realizing it through integrated structures. [0003] However, the above-mentioned patents only focus on higher power density without considering the current-carrying capacity of the transformer structure, so these patents cannot be effectively applied to common high-power working conditions. [0004] In addition, since the above-mentioned transformer structure does not consider the current bearing capacity of the transformer, the temperature rise is very significant during the implementation of the transformer, resulting in a decrease in transformer efficiency. Also, if an external heat sink is required to dissipate the heat, the intended high...
