DEVICE HAVING A POWER ELECTRONICS MODULE FOR SUPPLYING AN ELECTRIC LOAD OF A HOUSEHOLD APPLIANCE WITH ELECTRICAL SUPPLY VOLTAGE, HOUSEHOLD APPLIANCE, AND METHOD FOR PRODUCING SUCH A DEVICE

摘要

The invention relates to a device (1) for supplying an electrical load of a household appliance with electrical supply voltage, comprising a power electronics module (2), which has a hybrid circuit board (3) having a first circuit carrier (4) and a second circuit carrier (5), wherein a transition region (19) between the first and the second circuit carrier (4, 5) has a lower heat conductivity with respect to the first and/or the second circuit carrier (4, 5), and comprising a temperature protection device for the temperature protection of the power electronics module (2). On the first circuit carrier (4) of the hybrid circuit board (3), at least one semiconductor switch (6) is arranged, which is configured for generating the supply voltage for the electrical load. On the second circuit carrier (5) of the hybrid circuit board (3), a temperature sensor (8) of the temperature protection device for detecting a temperature is arranged, to which the at least one semiconductor switch (6) is subjected during the operation of the device (1). On the power electronics module (2), a thermally conductive foil (13) is arranged, by way of which the at least one semiconductor switch (6) and the temperature sensor (8) are thermally coupled to one another.
