The inverter may be a current source inverter, rather than a voltage source inverter (.Section 6.9.4) since it will be the rotor current that is required to be vtiried (equation (1.7)) to control the speed of a wound rotor motor, and this can be independently varied through the control of the rotor current. The speed and torque of the motor can be smoothly and steplessly controlled by this method, without any power loss. Figures 6.47 and 6.48 illustrate a typical slip recovery system and its control scheme, respectively. [Pg.141]

One conventional method to detect open switch faults in voltage source inverters is to transform the three line currents ia, i, ic into a domain with two currents id, iq and to study the shape of the trajectory iq vs id- An advantage of the method is that no further sensors are required. [Pg.197]

Section 8.2.3 also considers the effect of an abrupt parametric fault in one phase of the inverter s load. In this case study, the load of the three-phase inverter is an RL-network in delta configuration often used in studies of three-phase PWM voltage source inverters. The study may be extended by replacing the RL-network by a sophisticated BG-model of an induction motor (see for instance [31, Chap. 8]). Studies of the three-phase diode bridge rectifier typically assume a resistive load in parallel to a filter capacitor. [Pg.216]

The harmonic losses developed in the motor by the drive are very small in a typical mine hoist low speed synchronous motor powered from a Variable Speed Drive. In this type of configuration the Voltage Source Inverter (VSI) and Active Rectifier Unit (ARU) typically increase the motor losses by the order of 1-1.5% of the total motor losses. The low harmonic losses in this case is due to the motor s high reactance and low base frequency, the inverter technology and the switching frequency. [Pg.169]

The application of PWM Voltage source inverter drives to induction motors for mine hoisting applications is now a common solution for mine hoist drives. The drives have the benefit of having unity power factor, and can be designed to be compliant with the IEEE 519 guidelines for harmonic content. [Pg.201]

For a six-pulse Voltage Source Inverter (VSI), the inverter output voltage space vector can take any of seven positions in the plane specified by the d-q coordinates. The time integral of the inverter output voltage space vector is called the inverter flux vector for short. The d and q axis components of the inverter flux vector yf, are defined as... [Pg.183]
