Design-oriented analysis and performance evaluation of clamped-current-boost input-current shaper for universal-input-voltage range

In cost-sensitive off-line applications, compliance with the existing line-current harmonic standards can be achieved by employing clamped-current-boost (CCB) input-current shapers (ICSs). In this paper, a thorough analysis of the CCB ICS is presented, and a complete design-oriented mathematical model is derived. The design equations are given in closed forms so that they can be easily computed by any standard mathematical software. The model is verified experimentally on a 100 W universal-input-voltage-range ICS.
