摘要： A current inrush limiting technique for a switching power converter (100). In one aspect, a switching power converter includes a main power switch (106) and a current sensor. When the input current exceeds a second threshold, higher than the first threshold, a current-limiting resistance is coupled to receive the input current. Accordingly, the input current is limited in two stages by two different techniques. In another aspect, a bleed resistor receives current from a power source for providing power to a controller for the power converter. After start-up, such as when an output voltage of the power converter is available to provide power to the controller, the current limiting resistor is shorted and the bleed resistor is effectively removed. A single pin of an integrated circuit controller controls shorting of the current limiting resistor and removal of the bleed resistor.

摘要： A gate driver includes a variable strength driver circuit that provides an output signal to drive a high power device. The gate driver receives an update request from a host controller during an operating mode in which switching operations occur and updates one or more operating parameters associated with driving the high power device. The operating parameters including turn-on parameters, turn-off parameters, and soft shutdown parameters. The variable strength driver circuit uses the turn-on parameters for turn-on phases for the output signal, uses the turn-off parameters for turn-off phases for the output signal, and uses the soft shutdown parameters for soft shutdown phases for the output signal. The update request adjusts current, voltage, and/or time for one or more phases of the turn-on, turn-off and/or soft shutdown parameters.

摘要： Passive filters, line replaceable units and a modular power supply are provided. The passive filter comprises an inductor and a diode bridge. The inductor has a first end and a second end. The first end is coupleable to a phase output of an inverter. The diode bridge comprises a first diode and a second diode. The anode of the first diode is coupled to the second end of the inductor and a cathode of the first diode is coupleable to a positive DC bus voltage. The cathode of the second diode is coupled to the second end of the inductor and the anode of the second diode is coupleable to a negative DC bus voltage. The passive filter output is coupleable to cable(s) for an AC electric machine. A reverse recovery charge of the diodes achieves a target DV/DT for an output voltage of the passive filter at operating temperatures.
