摘要： A system for differential current monitoring includes a control module and a plurality of nodes operatively connected to the control module. Each node is configured to monitor current from a bus to a respective load. The control module and nodes are configured to monitor current at each of the nodes, issue a pulse for each node, wherein the pulse has a duration that is proportional to current at the node, concatenate all of the pulses for the nodes to determine the total current drawn from the bus at the nodes, compare the total current drawn from the bus at the nodes to current input to the bus, and signal a fault condition if the total current drawn from the bus is not within a predetermined range of the current input to the bus.

摘要： A power control module includes a power device having a first side and a second side opposite from the first. The power control module includes a printed wiring board (PWB) spaced apart from the first side of the power device. The PWB is electrically connected to the power device. A heat sink plate is soldered to a second side of the transistor for heat dissipation from the transistor. The PWB and/or the heat sink plate includes an access hole defined therein to allow for access to the transistor during assembly. A method of assembling a power control module includes soldering at least one lead of a power device to a printed wiring board (PWB), pushing the power device toward a heat sink plate, and soldering the power device to the heat sink plate.

摘要： A solid state power control (SSPC) controls flow of current from a power bus to an inductive load. The SSPC utilizes load sharing, in which a plurality of current supply paths are connected in parallel to control and share the flow of current between the power bus and the inductive load. Each current supply path includes a main power switching field effect transistor (FET); a balance resistor, and a secondary FET. The balance resistor is connected between the main FET and the load. The secondary FET shunts the balance resistor when the main FET is turned on, and allows current flow through the balance resistor during a turn-off time of the main FET. The balance resistor modulates gate-source voltage of the main FET in order to compensate for gate-source threshold differences among the main FETs that could lead to unequal current sharing during the turn-off period.
