Publication number: 20090174360Abstract: A method for reducing the influence of a DC component in a load current of an asynchronous three-phase motor, in which the voltages of two of the three phases are controlled by adjusting firing angles of semiconductor devices of the type turning-off at zero-crossing of the current therethrough comprises the steps carried out for each said controlled phase: detecting turn-off times of the semiconductor devices, calculating a value of a change of firing angle of the semiconductor devices needed for changing the length of the time period between two subsequent turn-off times for compensating for the influence of a DC component, and determining the firing angle of said semiconductor devices in dependence of the result of this calculation.Type: ApplicationFiled: March 11, 2009Publication date: July 9, 2009Inventors: Daniel Kling, Gunnar Johansson

Patent number: 7469017Abstract: The present invention discloses a double TRU (Transceiver Unit) (45). The output signals from the power amplifiers (64, 84) are combined to one common output signal provided to an antenna arrangement (91). A DSP (Digital Signal Processor) (52, 72) of each TRU (50, 70) comprises means for a constant-envelope modulation scheme (54, 74) and a non-constant envelope scheme (53, 73). The DSP:s (52, 72) select the modulation scheme according to modulation information (49, 69). In such a way, a switching between different modulation schemes can be performed even on a time-slot basis. For non-constant-envelope modulation, the modulated signal is separated into two component signals. Each TRU (50, 70) takes care of the amplification of one component. A phase compensation of at least one of the TRU:s (50, 70) is performed in order to correct for different paths of phases of the power amplifiers (64, 84). The non-constant envelope modulated signal can also be a multi-carrier signal, e.g.Type: GrantFiled: March 19, 2003Date of Patent: December 23, 2008Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Anders Granström, Gunnar Johansson
