查询词典 switches

Problems such as charge injection and clock feedthrough caused by turning off swithes are analyzed and solved in this design. The optimal switch sequence helps eliminate the nonlinearity caused by the charge injection; the addition of dummy switches to sensitive nodes caused by the clock feedthrough can greatly reduce the coupled charge; and the use of high PSRR folded cascode differential input stage can restrain the interference from the power supply. The circuit performance, therefore, has been greatly improved.

This thesis proposed the design and implementation of an ASIC for the motor control with DTC technology. Note that this ASIC is implemented by cell-based Design style with Verilog language.The basic principle of the Direct Torque Control is to select the switch sequence of the inverter. Those switches will control the magnetism and torque of the stator, to induce a fast response of the induction motor. Furthermore, the d-q axle's static coordinate, which is transferred from both the three-phase current and voltage, is used to compute the stator's magnetism and torque. By comparing with original values, those magnetism and torque will be calculated and set to new data. Then the switching table and the hysteresis controller are decided with the new data to generate a voltage vector and to control the stator magnetism and torque.

直接转矩控制的基本原理为经由侦测马达定子磁通与转子转速，来适当的选择变频器功率电晶体的切换状态，以获得快速且不易受外在环境影响的马达控制响应；首先，根据量测三相电流与利用变频器的切换状态取得马达的三相电压，将其转换至d-q轴静止座标，然后藉此估测马达的磁通量与转矩量，再分别与侦测的定子磁通量和转矩量比较后，得到定子磁通量与转矩量比较的结果，再利用DTC电压向量切换表(DTC Voltage Vector Switching table)，依定子磁通与转矩的比较值及马达所在的角度位置，来选择一个适当的电压向量，进而依切换顺序来激发功率电晶体，达到控制感应马达的目的。
