This paper presents a novel control method for controlling the Modular Matrix Converter (MMxC) in order to achieve balanced capacitor voltages in addition to load voltage and input current control. The proposed control technique has been designed based on independent current control of positive-, negative- and zero-sequence in addition to feed forward power control. The positive-sequence circuit is...
This paper compares the performance of hysteresis current control and space vector PWM operation of indirect field oriented controlled linear induction motor drive. Sliding mode control or standard PI controllers are applied in the outer control loop to control the mover speed. The inner control loops are standard PI controllers to regulate the direct and quadratic current components. The end effect...
Modern wireless communication standards, e.g. UMTS, are making use of modulation schemes, resulting in signals with high levels of peak-to-average power ratio (PAR). For example, the W-CDMA signal used in UMTS-standard has typical PAR levels above 6 dB. Conventional single-ended power amplifiers will result in low levels of average efficiency, if they were implemented in the transmitters of such communication...
