These power electronic based controllers can provide smooth, continuous, rapid and repeatable operations for power system control....

Signal generator which provide a variety of waveforms are referred to as unction generator. These are commonly available as test instruments. The variety of wave shapes provided generally determines the complexity and cost of the generator system. It facilitates such as voltage control of frequency and ability to provide a signal wave or group of the wave. Function generator system can be readily synthesized using operational amplifiers on an approach which uses full when the need for a special purpose generator arises or when a function generator is inconvenient or prohibited by cost consideration....
