| 摘要 |
The invention relates to a power electronic apparatus, and especially a converter apparatus, which consists of individual electrical functional units such as a power section, power supply section, drive section and control section or their combinations (b, c) and a cooling body (a), also used as a supporting body, which supports the power electronic components; it is characterised in that - the electrical functional units (b, c) are constructed in accordance with their circuit, structurally isolated from one another, - each electrical functional unit (b, c) has side parts (1b, 2b; 1c, 2c) on at least two opposite sides (1, 2), the side parts (1b, 2b; 1c, 2c) of all functional units (b, c) having means (3) for their detachable connection to one another on the edges on which they are connected to one another, and the functional units (b, c) having equal or different step widths, corresponding to their internal construction, and being detachably connected to one another via the means (3), - the cooling body (a) is connected to two mutually opposite side parts (1a, 2a) and forms the supporting body of the power electronic apparatus, - the side parts (1a, 2a) are connected to the adjacent functional unit (b) via means (3) for detachable connection, and - the side parts (1a, 2a) have a step width corresponding to the dimensions of the cooling body (a), including the power electronic components. <IMAGE> |
