Embodiment Construction

[0010] The DC-DC in the present invention is a DC-DC converter, which is a high-power-density DC-to-DC power converter suitable for hybrid vehicles, and belongs to a switching power supply. The present invention includes a DC-DC control board 10 and an IMS insulated metal power board 20, which are connected and fixed by a transition part, and the DC-DC control board 10 and the IMS insulated metal power board 20 are connected between the two boards. The drive control lines 30 are connected through connectors, and all high-voltage circuits are on the IMS insulated metal plate 20 .

[0011] The DC-DC control board 10 is designed separately from the IMS (Insulating Metal Substrate) insulated metal power board 20, and the DC-DC control board 10 and the IMS insulated metal power board 20 are installed opposite to each other, as shown in Figure 1, providing good electrical performance. High and low voltage isolation measures, the DC-DC conversion system can accept control instruction...

Abstract

A DC-DC converter used on mixed power vehicle is prepared as using transition component to connect and fix DC-DC control board and IMS insulation metal power plate, connecting a driving control line between said control board and metal power plate by pluggable unit and arranging all high voltage circuits on IMS insulation metal plate.

Description

technical field [0001] The DC-DC in the present invention is a DC-DC converter, which is a high-performance DC-to-DC power conversion device for hybrid vehicles. Background technique [0002] At present, the problem of shortage of oil resources is becoming more and more serious, and it has become a consensus among people to reduce the fuel consumption of vehicles. However, people are unwilling to sacrifice greater vehicle power. The contradiction between the two is almost impossible to resolve in traditional internal combustion engine vehicles. Therefore, people are constantly looking for other ways. High-efficiency, energy-saving, and environmentally friendly clean cars have become a new trend in the development of the automotive industry. Although it is generally believed that pure electric vehicles are the best product for clean cars, current battery technology problems hinder the application of electric vehicles. Since the energy density of the battery is hundreds of t...
