A Low Cost Sensorless Control Drive Circuit for of Low Voltage Switched Reluctance Motor
Shaft position sensing is an essential part of switched reluctance (SR) motor drive In order to synchronize the pulses of phase current with the period of rising inductance of the proper motor phase. Direct sensors such as, Hall effect and optical encoder are commonly used in SR motors. The purpose of this paper is to present an indirect shaft positioning sensing known as "sensorless " control ...
متن کاملAF Compact Low - Voltage Circuit Breakers
In order to protect wiring, facilities, human bodies and the like from electric accidents such as overcurrent to the load, a short circuit, ground fault or earth leakage of an electrical line, low-voltage circuit breakers, as typifi ed by molded case circuit breakers (MCCB) and earth leakage circuit breakers (ELCB), are installed in every type of machine, equipment, facility and building that u...
متن کاملLow Voltage SC Circuit Design with Low - MOSFETs
In this paper, low threshold voltage (Vt) “natural” transistors, available in some n+/p+ dual poly gate CMOS/ BiCMOS processes [1], are proposed for low voltage switched capacitor circuit design. The impact of the subthreshold off-current of these low devices on the performance of analog switched-capacitor (SC) circuits is analyzed. Methods for reducing the subthreshold offcurrent in analog swi...
متن کاملA benzotrithiophene - based low band gap polymer for polymer solar cells with high open - circuit voltage †
novel electron-rich fused aromatic unit, namely benzo[1,2-b:3,4b’:5,6-d’’]trithiophene (BTT), which holds promise as a building block for semiconductor materials. In comparison with the wellknown benzo[1,2-b:4,5-b’]dithiophene (BDT), quantumchemical calculations (B3LYP/6-31G*) predict the BTT unit to 40 be of similar donor strength. Thus, with R being alkyl chains, BTT is predicted to act as a ...
