a second quadrant power section including power devices connected from the second power substrate to the fourth power substrate,

a third quadrant power section including power devices connected from the third power substrate to the fifth power substrate,

a fourth quadrant power section including power devices connected from the fourth power substrate to the sixth power substrate,

a first power contact connected to the first power substrate;

a second power contact connected to the second power substrate;

a third power contact connected to the third power substrate;

a fourth power contact connected to the fourth power substrate;

a fifth power contact connected to the fifth power substrate;

a sixth power contact connected to the sixth power substrate;

a first gate source interconnection substrate connected to at least one power device, the first gate source interconnection substrate including a first gate contact and a first source contact;

a second gate source interconnection substrate connected to at least one power device, the second gate source interconnection substrate including a second gate contact and a second source contact;

a third gate source interconnection substrate connected to at least one power device, the third gate source interconnection substrate including a third gate contact and a third source contact;

a fourth gate source interconnection substrate connected to at least one power device, the fourth gate source interconnection substrate including a fourth gate contact and a fourth source contact;
