Development Status Of Rectifiers

At present, the industry launch of energy-saving lamp and electronic ballast dedicated transistors are very much focused on control of the storage time. TS because the storage time is too long, the oscillation frequency of the circuit will drop, increases the operating current of the machine can cause damage to transistors. Although you can adjust the choke coil inductance parameters and other components to control the power, but TS discreteness, will make poor product consistency, reliability of decline. For example, quartz lamp electronic transformer circuits, storage time is too large may cause circuit of transistors below the output transformer limit the frequency of oscillation, resulting in a magnetic core saturation at the end of each cycle, which makes transistors, Ic peak occurs in every cycle, and cause the device to overheat damage (Figure 3).
