Garenth Lim King Hann Electrical Three-Phase Power System Battery Electric Vehicles (BEV) Battery Charger What is single phase system? Single phase electric power system is the basic alternating current (AC) electric power in which the voltage and current flow changes in magnitude and direction in a cyclical fashion, typically 50 or 60 times per second. *four poles single phase system Review on Single Phase System Vmax ωt v(t ) = Vmax sin t - Vmax is the amplitude of the wave - ω is the angular frequency of the wave Theory of AC signal A B T 1 Average: vave = Vmax sin t dt = 0 T 0 2 ( ) T Vmax 1 RMS: vrms = Vmax sin t dt = T 0 2 Polar Form Representation Z = x + jy = A = A(cos + j sin ) Z=A
