摘要： A method and an apparatus for measuring the output currents of a frequency converter, preferably a vector-controlled frequency converter, which comprises a mains bridge (10) connectable to an alternating-current network and a load bridge (11) connectable to an alternating-current load and between these a direct-voltage intermediate circuit, by using current samples obtained from a current measuring sensor in the intermediate voltage circuit, wherein a sample is taken from the signal of the current measuring sensor substantially simultaneously with a point of change of the output voltage vector and upon the lapse of a predetermined delay after the point of change after the switching effects have settled.

摘要： Method and apparatus for controlling an apparatus transmitting power between two electricity networks or between an electricity network and a polyphase electric machine (M/G), which electricity networks can be polyphase alternating-current networks or one of them can be a single-phase direct-current network, and which apparatus comprises low-voltage power cells (C), which comprise a single-phase output connection (OUT). The power cells also comprise a single-phase input connector (IN), the power cells are arranged into groups (G 1 - G N , G P1 - G PN1 , G S1 - G SN2 , G 1 "'- G N "') such that at least one power cell per each phase of the electricity network or of the electric machine belongs to each group, and the input terminals (IN) of all the power cells belonging to the same group are connected to a common transformer, which transformer comprises its own separate winding that is galvanically isolated from the others for the power cell connected to it. The controllable power semiconductor switches connected to the input connectors (IN) of all the power cells supplying power to the same transformer are controlled essentially cophasally with a 50% pulse ratio.

摘要： Method and arrangement for controlling the output voltage pulses of a PWM frequency converter, in which PWM frequency converter is a network bridge (10) for rectifying the alternating voltage of the supply network into the DC voltage (U DC ) of the DC intermediate circuit, which is filtered with a filtering capacitor (C DC ), a load bridge (11) comprised of phase switches implemented with power semiconductor components, which forms the AC output voltage (U, V, W) from the DC voltage of the intermediate circuit for controlling the load (M), in which for setting the average speed of change in the output voltage in connection with each change of state of the output voltage at least one power component controlled by a phase switch is controlled such that before the output voltage remains in its position subsequent to the change of state it is on at least once for a short period, typically of less than 1µs (a micropulse), in the position prevailing before the change of state.

摘要： An electrical energy supply system comprises at least one asynchronous generator (101) and a converter system (102) connected to the electrical terminals of the asynchronous generator. The converter system is configured to convert the voltages of the asynchronous generator into voltages suitable for an external system to be supplied by the electrical energy supply system. The electrical energy supply system further comprises capacitors (103) connected to the electrical terminals of the asynchronous generator at least during starting of the asynchronous generator. The capacitors are suitable for exciting the asynchronous generator during the starting. Thus, there is no need for a control arrangement for controlling the converter system to excite the asynchronous generator during the starting.
