Abstract
Design and packaging of wide bandgap (WBG) power electronic power stages are disclosed herein. An example apparatus includes a first printed circuit board (PCB) including: a first voltage phase circuit cluster; a second voltage phase circuit cluster; and a cluster of traces, the cluster of traces routed substantially perpendicular to the second voltage phase circuit cluster; a second PCB positioned below the first PCB; and a connector to connect the first PCB to the second PCB, the connector electrically coupled to the first voltage phase circuit cluster by the cluster of traces.
Claims21
An apparatus comprising:
- a first printed circuit board (PCB) including:
- a first voltage phase circuit cluster;
- a second voltage phase circuit cluster;
- and
- a cluster of traces, the cluster of traces routed substantially perpendicular to
- the second voltage phase circuit cluster;
- a second PCB positioned below the first PCB;
- and
- a connector to connect the first PCB to the second PCB, the connector electrically coupled to the first voltage phase circuit cluster by the cluster of traces.
An apparatus comprising:
- a power switching assembly having a rear face;
- a capacitor bank having a top side and a front face;
- and
- a bus bar having first and second subregions, the first subregion positioned above the capacitor bank with an approximately congruent surface area to that of the top side of the capacitor bank, the second subregion curving along the front face of the capacitor bank and extending into a cavity between the capacitor bank and the rear face of the power switching assembly.
An apparatus comprising:
- a baseplate of a power switching module including channels engraved therein;
- and
- a manifold contacting the channels, the manifold configured to receive coolant from a pump at an inlet and to cause jet impingement of the coolant as the coolant flows through the channels.
