Many drives have most of the components, except for the caps, within the IPM (integrated power module).
The rectifier will be a "six-phase" configuration (three-phase full-wave), employing six diodes in a three-phase drive, and will be a "two-phase" configuration (single-phase full-wave), employing four diodes in a single-phase drive.
Voltage-doubler drives are known, and these have twice as many caps, but also a direct connection between one line, usually N, and the center of the cap bank, with equal number of caps in parallel on either side of this connection.
It is possible to make a 120/240 drive, but I've not seen such a drive in practice. Conceptually, this connection would be present in a 120-to-240 drive, but absent in a 240-to-240 drive.
Manufacturers usually leave very few options available to the end-user, save programming provisions.
A negative TEMPCO resistance follows the diodes, and this comprises the "soft start" circuit.
The capacitors across the DC bus are after this "soft start" circuit.
In 230 volt drives, capacitors are usually rated 450 volts (325 volt dc bus) and 105ºF. In 460 volt drives, two caps are placed in series to obtain a 900 volt rated cap (650 volt dc bus).
The boards may be laid out to accommodate multiple paralleled caps.
One design I am familiar with has places for six caps, but on a standard unit only four are "stuffed", leaving two positions empty.
In this same design, all components, except for the caps, are within the IPM, and it is, therefore, impossible to effect a "component level repair", save for the caps.
The one "raw" board is applicable to several models, with each variation having a different number and capacity of caps, and/or a different IPM.
One "raw" board per frame size is theoretically possible.
If one cap has failed, all should be replaced as the exact failure mode might not be immediately apparent.
