Problems solved by technology

In addition, all the coils are wound around the middle leg CC with the largest circumferential length (ie W1>W2, W3), which is disadvantageous in terms of the material constituting the coils and prolongs the current movement path, which is harmful to heat generation and Not ideal in terms of efficiency

Embodiment Construction

[0041] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. For the convenience of description, the suffixes "module" and "unit" of elements are used herein, and thus these suffixes can be used interchangeably without any distinguishable meaning or function.

[0042] In describing embodiments, it will be understood that when an element is referred to as being "on or under" or "in front of or behind" another element, this includes situations where the two elements directly contact each other and at least one other element is placed between the two elements.

[0043] Also, terms such as 'first', 'second', 'A', 'B', '(a)' and '(b)' may be used when describing components of the present disclosure. These terms are used only to distinguish one component from another, and the terms do not limit the nature, order or sequence of components. When it is said that a component is "connected", "...

Abstract

The present invention relates to a transformer and, more specifically, to a transformer including a secondary coil part which comprises stacked conductive plates. A transformer according to an embodiment of the present invention may comprise: a core part having a middle leg and outer legs; a secondary coil part including multiple conductive plates vertically stacked to form coil turns around the middle leg; and a primary coil part including conductive wires wound to form coil turns around the respective outer legs.

Description

technical field [0001] Embodiments relate to a transformer having a secondary coil unit including stacked conductive plates and a DC-DC converter including the same. Background technique [0002] With the recent continued attention to the environment and environmental regulations, research on vehicles having electric motors has been actively conducted. Generally, such vehicles are provided with a high-voltage battery configured to drive an electric motor and an auxiliary battery configured to supply electric power to electronic loads. The auxiliary battery can be charged with power from the high-voltage battery. In order to charge the auxiliary battery, it is necessary to convert the DC power of the high-voltage battery into DC power corresponding to the voltage of the auxiliary battery. For this purpose a DC-DC converter can be used. [0003] figure 1 is a block diagram showing one example of the configuration of a general DC-DC converter. [0004] refer to figure 1 ,...
