| Popis: | The development of techniques for integrated circuits has driven their miniaturization. The reactance components of converters can be miniaturized by using high switching frequency. Therefore the resonant converters are useful because of the low switching loss in semiconductor switches. At the resonant converters, raising or lowering of output voltage is fundamentally controlled by the switching frequency. For high frequency switching in main switch, high frequency driver is required. However, it is difficult to obtain comparators capable of high frequency operation. To overcome this, we have examined the self-excitation LC oscillation circuit for its use in the main switch drive circuit. It is important to consider the Miller effect of MOSFET about the self-excitation LC oscillation circuit analysis. In the practical circuit, variable capacitance diodes can be included in the resonant circuit. The dc voltage from outside can control the output of the converter. |
