Overview of Technology State

Role of power electronics and drivers
  • Power controlling using electronics consider here
  • Signal controlling is consider about controlling information
Power electronics is about control of power electronically. Range of power can extend from some fraction of watt to several mega watts (MW). Drives are about the control of mechanical motion. It can be a linear motion, rotary motion or their combination. There is a greater compatibility between power electronics and drives as the former can provide smart control of power for the drives. This is evident from the varieties of fascinating motion control systems we find today.

There are several terms used in the context f motion control.
  • Motion control systems
  • Mechatronic systems
  • Drive systems
  • Adjustable speed drive systems
  • Servo drive systems
Motion control system is the name used in west (Europe) to represent the low power drives (Computer pheripherals, home appliances...etc) upto several KW. Mechatronics system is the name used in the east (Japan) for the same, that is the low power drives. Drive system is the name that represent drives of the entire sprectum of power. Adjustable speed control system is the name reserved for the sub category whose steady-state performance only is emphasize. Servo drives in the name reserved for another sub category whose both the transient and the steady-state performance are empasized.

Automation is a multidisiplinary technology that integrates the knowledge of diverse areas such as instrumentation, remote sensing, advance control, data processing, computer technology, microelectronics, mechanics process system, motion control and many more. Motion control is one of the thrust areas that propells automation industry hard.

Power Electronics And 3Phase Drives

3 Phase motor drives and DC drives dominate the industry in most applications from low to high power. (Single phase drives usually take care of the low power end.) Basic 3Phase motors are: 3Phase induction cage rotor motor 3Phase induction wound rotor motor 3Phase synchronous motor 3Phase induction motors are used widely to serve general purpose applications, both adjustable speed and servo drives. 3Phase synchronous motor is found in special applications, mostly as servo drives. Some very large power adjustable speed drives also prefer synchronous motors because of the possibility of using low cost load-commutated-inverters (LCI) built from thyrestors.

Single Phase Drives - Servo Control Mode

Servo control use current control for rapid adjustment of motor torque. Voltage control will not be good for servo applications due to inherent delays before the control passes to adjust current. In PWM it is a delay in the motors electrical time constant L/R; in square wave control it is a sequence of delays at the capacitor of DC-link, electric time constant L/R of motor etc. To obtain current control we use, so called, "current controlled PWM". There too, we have two options; (a). Hysteresis current control mode (b). Fixed frequency current control mode (a). Hysteresis current control mode This PWM acts to constrain the motor current I to a specified shape and amplitude, as suggested by the outer loops (e.g. Speed loop) of the closed loop control system. This requires motor current feedback as an input to the PWM modulator. Desired current is the other input.Switching principle is,

Single Phase Drives - High Speed Control Mode

This mode of control is suitable when the speed is to be controlled at higher values; for example above base speed. At higher speed the motor will not response to torque harmonics (because of filtering due to electromagnetic time constant) and hence we can apply simple square wave voltage input. The motor then responses to the fundamental component of voltage and (virtually) ignores harmonic voltages. Switching pattern for squarewave voltage output Ts - Switching cycle time.
