the Silicon Controlled Rectifier (SCR) in 1957 has initiated the application of solid state devices in power converters. The development of the electrical drives systems can be divided into three stages Before power semiconductor devices were introduced: AC drives were used for fixed speed operation. Generating an AC voltage with variable frequency was only possible by using rotary converters‚ which are bulky and inflexible. Although it is possible to use variable voltage with fixed frequency sources

digital implementation of a linear control technique for single-phase boost power factor correctors (PFC). Such converters present nonlinear characteristics and an approximation of them are used to drive the models. The most important result obtained is that the small-signal output is not equal to the load impedance. The proposed circuit significantly improves the dynamic response of the converter to load steps without the need of a high crossover frequency of the voltage loop by adding low-pass filter
