On the other hand, negative base current IB2 must be provided the transistor to turn off (retrace phase). Most of the dissipation, especially in the deflection application, occurs at switch-off so it is essential to determine the value of IB2 which minimizes power losses, fall time tf and, consequently, Tj. A new set of curves have been defined to give total power losses, ts and tf as a function of IB1 at 64 KHz scanning frequencies for choosing the optimum drive. The test circuit is illustrated in figure 1. The values of L and C are calculated from the following equations: 1 1 L (IC)2 = C (VCEfly)2 2 2 1 ω = 2 πf = L  √C Where IC= operating collector current, VCEfly= flyback voltage, f= frequency of oscillation during retrace. 4/7 BUH1015HI Figure 1: Inductive Load Switching Test Circuit.
