Abstract: PWM control technique——current controlled pulse width modulation technique proposed by A.G. Bose, et al ,and its application in power converters are introduced and analyzed, and the stability problem of a current controlled pulse width modulation system is discussed. The experiments show that this kind of power converter has the following advantages:light weight, small volume, high static accuracy, and fast transient response; it is of very important application value in engineering.

Key words: current requlators, power converters, pulse width modulation
