Power modules for circuit protection

An electronic device, comprising:

• a plurality of electronic modules;
• a control circuit connected to the plurality of electronic modules;
• and
• a frame providing mechanical support to and electrical connections between the plurality of electronic modules and the control circuit,
• wherein each electronic module among the plurality of electronic modules comprises:
• a plurality of first field effect transistors (FETs);
• a plurality of second FETs, each second FET of the plurality of second FETs pairing with a respective first FET of the plurality of first FETs;
• a controller, connected to gate nodes of the plurality of first FETs and the plurality of second FETs;
• and
• a plurality of spring assemblies, disposed between the plurality of first FETs and the plurality of second FETs and pairing with the respective first FETs of the plurality of first FETs,
• wherein each spring assembly of the plurality of spring assemblies comprises a disc spring that is clamped and at least one conductive path that connects both ends of the spring assembly, each spring assembly has two ends, wherein one end is connected to a press-buffer that contacts at least one first FET and the other end is connected to another press-buffer that contacts at least one second FET,
• wherein drain nodes of the plurality of first FETs are connected to a first electrode plate, and drain nodes of the plurality of second FETs are connected to a second electrode plate;
• and
• wherein each source node of the plurality of first FETs is connected to one end of a respective spring assembly, and each source node of the respective plurality of second FETs pairing with the plurality of first FETs is connected to the other end of the respective spring assembly.
