The single-phase uncontrolled rectifier supplying a constant power load (CPL) is common in a power system, especially for digital devices such as telecommunication equipment. The characteristics of CPLs may de-stabilize the system and cause the output voltage collapse if the initial capacitor voltage is too low. Based on a mathematical model of the rectifier-CPL circuit, a method is proposed to estimate the minimum initial voltage. Also, some non-linear factors including the source impedance and the inertia of the CPL. When the rectifier operates in steady states, a high load power may cause the bifurcation phenomenon. Some analysis is made for the bifurcation and its negative effects on the power grid.
