摘要： The disclosure relates to a method for charging an intermediate circuit capacitor in an electric drive unit comprising an electric motor. The intermediate circuit capacitor is charged by an intermediate circuit current that is supplied by a battery. The output voltage of the battery is settable to one or more voltage values. A target value of the intermediate circuit current is determined, and an actual value of the intermediate circuit current is ascertained. The actual value of the intermediate circuit current is then compared with the target value of the intermediate circuit current. An optimal output voltage of the battery is determined on the basis of the comparison of the actual value of the intermediate circuit current with the target value of the intermediate circuit current. Then, the optimal output voltage of the battery is set.

摘要： Systems and methods for controlling potentially damaging inrushes of current to the capacitor bank of an electric drive system when the voltage on the capacitor bank is low. In one embodiment, a variable speed drive has a converter that converts AC power to DC power, a capacitor bank that receives the DC power, and an inverter that converts the DC power stored by the capacitor bank to AC output power. The converter has three sections that rectify the phases of three-phase input power. Each section has at least one controlled rectifier component, and the rectifier components have switches connected to them in parallel. When the voltage on the capacitor bank is low, the controlled rectifiers and switches are controlled to prevent dangerously high inrushes of current to the capacitor bank.

摘要： The invention comprises a high frequency inductor filter apparatus coupled with an inverter yielding high frequency harmonics and/or non-sixty Hertz output. For example, an inductor/converter apparatus is provided that uses a silicon carbide transistor to output power having a carrier frequency, modulated by a fundamental frequency, and a set of harmonic frequencies. A filter, comprising an inductor having a distributed gap core material and optional magnet wires, receives power output from the inverter/converter and processes the power by passing the fundamental frequency while reducing amplitude of the harmonic frequencies.
