Power conversion device

Abstract

A power conversion device includes a main board, an electromagnetic interference filter module, an auxiliary power module, a capacitor group, a main power unit, a control plate, an output bus bar and a fan. A first air channel is formed between the auxiliary power module and the electromagnetic interference filter module. A second air channel is formed between two rows of the capacitor group. A third air channel is formed between the two main power conversion modules of the main power unit. The control plate is perpendicularly installed on the main board. The output bus bar is perpendicularly installed on the main board, arranged in parallel with the control plate and located near the control plate. The fan is located near the main power unit and producing airflow to the first air channel, the second air channel and the third air channel.
