this paper proposes a new configuration for solar energy conversion systems. one challenging issue of the photovoltaic (pv) systems is partial shading, and in this paper module integrated converters (mic) are used to overcome this problem in pv arrays. a few boost converters are employed as mics to mitigate the shading effect. furthermore, to reduce the cost and to increase the system performan...

This paper deals with the Direct Torque Control (DTC) of Brushless DC (BLDC) motor drives fed by four-switch inverters (also known as B4inverters) rather than six-switch inverters (also known as B6 inverters) in conventional drives. The principle of operation of the BLDC motor is firstly recalled considering both cases of B6and B4-inverters in the armature, with emphasis on the twoand three-pha...

This paper proposes a new configuration for solar energy conversion systems. One challenging issue of the photovoltaic (PV) systems is partial shading, and in this paper Module Integrated Converters (MIC) are used to overcome this problem in PV arrays. A few boost converters are employed as MICs to mitigate the shading effect. Furthermore, to reduce the cost and to increase the system performan...

The sensorless model predictive force control (SMPFC) is a strong method for controlling the drives of three-phase 4(6)-switch inverter linear induction motors. This kind of inverter can be employed for fault tolerant control in order to solve the problem of open/short circuit in 6-switch inverters (B6). This paper proposed a method for the SMPFC of a linear induction motor (LIM) with a 4-switc...

in this paper, a new topology for boost z-source inverterbased on switched-inductor cell is proposed. the operating modes of the proposed inverter are analyzed and also a suitable control method to generate the trigger signals of the inverter is presented. having a common earth between the input source and inverter and capability to generate a higher voltage gain by using lower amounts of the d...

Spleen cells of b4b6 rabbits, shown to be deficient in their ability to produce b4Ig due to prenatal exposure to anti-b4, formed anti-T2 antibodies marked with the b4 determinant in response to solubilized T2 phage (S-T2) only when cultured in the presence of antibodies specific for the nonsuppressed type (b6), thus confirming and extending the previously reported observation of release from b4...

CD19 (B4) is a signal transduction molecule restricted to the B-cell lineage and the target of the immunotoxin anti-B4-blocked ricin (anti-B4-bR), which is composed of the monoclonal antibody (MoAb) anti-B4 and the modified plant toxin blocked ricin. To explore the influence of conjugation of blocked ricin to anti-B4 on functional activation of CD19, we investigated the effects of anti-B4-bR, a...
