The use of spatial vector pulse width modulation (SPWM) with triangular comparison is proposed to increase the qSBI gain factor, and its performance is contrasted with other types of spatial vector modulations, such as discontinuous modulations. To verify the validity of the method for voltage range extension in the qSBI converter, a semi-customized test platform was developed. This platform uses a DSP floating point card (Analog Devices ADSP-21369) for processing and control strategies and an interface card that includes a programmable logic array (FPGA) from Xilinx (Spartan-3), which allows to develop the synchronized modulation qSBI needs. The experimental results show improvements in the performance of the qSBI converter in terms of gain factor, voltage reduction in the capacitor, and input current profiles.

The first method uses the Direct Torque Control (DTC), employed frequently on speed regulation of the AC machines. The second one proposed by authors, uses the optimization of the space vector voltage in a controller bridge to reduce the least square error by controlling the instantaneous active and reactive power. These control methods have several advantages and disadvantages and are combined to improve the static and dynamic Direct Power Control (DPC) performance. The new proposed control system is no affected by harmonic distortion in the network and the obtained regulation of active and reactive power flow is practically instantaneous (< 10 ìs ) as is shown by performed simulations.
