摘要： A conventional ground fault interrupter in an arrangement with a frequency converter and electrical machines may be accidentally tripped due to operation-related leakage currents. This can be prevented by operating a ground fault interrupter for a frequency converter receiving a mains current in the following manner: receiving switching information about switching operations in the frequency converter, measuring a signal associated with a common mode current in a power line device which conducts the mains current to the frequency converter, determining, based on the switching information, an expected signal expected for the common mode current produced by the switching operations, identifying, based on the measured signal and the expected signal, a fault current, and interrupting the mains power depending on the identified fault current. A ground fault interrupter is hereby provided with an evaluation unit configured to carry out the method.

摘要： The invention relates to a method for determining the chance of a disturbance-free operation of a frequency converter (2) connected to a feeding network (18). According to the invention, during the operation of said frequency converter (2), an intermediate circuit voltage (UZK) is continuously measured and a network-side intermediate circuit current (iZKmains) is continuously determined; these measuring quantities are compared with pre-determined operating values of the frequency converter (2), and quantities which are higher or lower than said values are respectively stored; and the frequency (Hij) of said higher and lower measuring quantities is determined and converted into a characteristic number for the quality of the feeding network (18). As said characteristic number decreases, the chance of a disturbance-free operation of the frequency converter (2) increases. In this way, a frequency converter (2) is able to detect the risk of appliance disturbance or failure as a result of network disturbances before the operation is interrupted

摘要： A method for controlling a matrix converter with nine bidirectional power switches arranged in a 3×3 switch matrix is described. Switching states of a modulation period are each calculated with associated time intervals by using a space vector modulation method. According to the invention, these calculated switching states are each divided into switching states of an output phase of the matrix converter, with time intervals assigned to the switching states, wherein the time intervals and the output-phase-related switching states are placed into one-to-one correspondence. Depending on the measured input voltages, the output-phase-related switching states with associated time intervals are combined into a pulse train of a modulation period, so that a sequential commutation always occurs to a nearest input voltage. This significantly reduces the switching losses of a matrix converter.

摘要： In a frequency converter operated for safety of personnel and/or fire protection via a ground fault interrupter is frequently not able to distinguish between an actual fault current and an operationally generated leakage current. The proposed method addresses this problem by determining a course of a magnitude of a current flowing through the frequency converter, predefining a signal portion which is independent of switching processes within the frequency converter while the frequency converter operates fault-free, checking whether the determined course satisfies a criterion that is predetermined depending on the signal portion, and interrupting the current the determined course fails to satisfy the predetermined criterion.

摘要： A drive controller for a self-commutated converter providing a “safe stop” is described. The converter has two half-bridges, and the drive controller includes two control circuits having outputs operatively connected to respective converter valves of the half-bridges. Pulse inhibiting controllers are associated with the control circuits in one-to-one correspondence. The drive controller further includes a plurality of switches, each switch defining a disconnectable pulse inhibiting path and receiving control signals from one of the pulse inhibiting controllers. Each of the pulse inhibiting paths has an input which is connected to an external voltage, and an output which is connected, on one hand, via a diagnostic line to a corresponding pulse inhibiting controller and, on the other hand, to a control input of the corresponding control circuit. The switches can therefore be cyclically tested without service interruption.
