Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/173379
Kind Code:
A1
Abstract:
In order to configure a power conversion device to have a small size and a small weight while inhibiting accumulation of dust, this power conversion device comprises a housing (100) having formed therein a first compartment (SP1) accommodating a first main circuit board (122), a second compartment (SP2) having an airflow passage for allowing cooling airflow to pass therethrough, and a third compartment (SP3) accommodating a second main circuit board (162), wherein: electric terminals (124a) of first capacitors (124) and electric terminals (126a) of first semiconductor elements (126) are accommodated in the first compartment; at least a part of each of the first capacitors (124) and at least a part of each first heat sink (128) are exposed in the second compartment; electric terminals (164a) of second capacitors (164) and electric terminals (166a) of second semiconductor elements (166) are accommodated in the third compartment; and at least a part of each of the second capacitors (164) and at least a part of each second heat sink (168) are exposed in the second compartment.
