摘要： The invention relates to the controlling of a multi-phase rectifier for adapting the temperature distribution in the rectifier. According to the invention, the phase currents in the individual phases are adjusted on the output-side of the rectifier with a different amplitude. Correspondingly, the respective half bridges in the rectifier are loaded to a differing degree. In this way, an uneven temperature distribution can be compensated in the rectifier. Alternatively, an uneven temperature distribution can also be adjusted in the rectifier in a targeted manner, in order to take further parameters into account.

摘要： The invention relates to a method for estimating a temperature contribution of an inverter used to energize an electrical machine, in particular a synchronous machine. The method comprises the steps for calculating oscillating temperature swings of components of the inverter; and determining, as the estimated temperature contribution (ΔT(ω), ΔTi(ω), (ΔTd(ω)) of the inverter, an upper envelope of an amplitude of a sum of the calculated oscillating temperature swings. The method according to the invention or an apparatus designed to carry out the method can be expanded for the purpose of estimating a temperature or a complete temperature contribution of the inverter and is provided, in particular, for use in an electric vehicle or a hybrid vehicle having an electrical drive without a variable speed gear in order to estimate the operating temperature of vehicle drive power electronics accommodated therein.

摘要： The present invention relates to a variation of the clock frequency for pulse-width-modulated actuation of an electrical converter. In this context, the clock frequency can be specifically lowered in an angle range of an electrical period of an AC current to be output. The specific lowering of the clock frequency during predetermined angle ranges of the electrical period allows the load on the switching elements in the converter to be adjusted. As a result, it is possible, by way of example, to adjust the temperature distribution or thermal load in the converter.

摘要： The invention relates to the controlling of a rectifier with multiple electrical phases. In at least one electrical phase, the duty cycles are merged with one another in two consecutive cycles of the pulse-width modulated controlling, i.e. in a first PWM-pulse, the duty cycle is shifted to the end of the PWM-pulse, and in a subsequent PWM-pulse, the duty cycle is shifted to the start of the PWM-pulse. As a result, there must be no switching process between two consecutive PWM-pulses. In this way, the switching losses and consequently the rise in temperature of the rectifier can be minimised.

摘要： Embodiments relate to a control device for an electric motor having at least one phase. The control device includes a power unit having a first switching element and a first flyback element corresponding to the first switching element and a second switching element and a second flyback element corresponding to the second switching element. The first switching element is designed to couple a corresponding power connection of the motor with a positive supply voltage. The second switching element is designed to couple the corresponding power connection of the motor with a negative supply voltage; and a control unit designed to separately detect a first current flowing through the first switching element or second switching element corresponding to the phase, to detect a second current flowing through the flyback element corresponding to the respective second switching element or first switching element, and to control the switching elements of the power unit.
