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.
