Abstract

In recent years, most electronic devices are miniaturized because the technique on integrated circuits has been developing. Switching power supplies become small-sized by using high switching frequency to decrease the size of reactance components. The resonant converters are useful because of the low switching loss in semiconductor switches. LC oscillators are suitable for VHF gate driver in resonant converters. In this paper, an analysis on oscillation conditions of a 110-MHz self-excitation gate driver based on class-Φ2 inverter is reported. The oscillation frequency characteristics and the conditions for oscillation are analyzed in detail including the influence due to the internal capacitances of switching devices.
基于Φ2谐振逆变器的甚高频自振荡栅极驱动器的振荡条件分析
近年来,由于集成电路技术的不断发展,大多数电子器件都向着小型化方向发展。利用高开关频率减小电抗元件的尺寸,使开关电源小型化。谐振变换器是有用的,因为在半导体开关的低开关损耗。LC振荡器适用于谐振变换器中的甚高频栅极驱动。本文分析了基于-Φ2类逆变器的110 mhz自激栅极驱动器的振荡条件。详细分析了开关器件的振荡频率特性和产生振荡的条件,包括开关器件内部电容的影响。
