Therefore, the final magnetization direction of zero-dc-field switching can be determined by the rotation direction of the microwave field despite the fact that \(-z\)- and \(+z\)-direction magnetization is energetically equivalent. This one-way magnetization switching is confirmed in Fig. 3b,...

Abstract A zero-voltage-switching (ZVS) DC-DC converter is proposed. Based on a bridge-type constructer, a coupling capacitance Cb is added in parallel with two series-connecting primary windings. Thus the synchronous operation of the two primary windings and current-sharing can be realized. The...
摘要: A nonisolated coupled-inductor-based high step-down converter with zero dc magnetizing inductance current and nonpulsating output current is presented. Since the dc magnetizing inductance current is zero, the magnetizing current can be positive and n......
The clock generator maintains zero DC level and minimum reverse bias voltage swing at high microwave and millimeter wave frequencies. Proper phase shift between the fundamental and second harmonic waveforms produces the desired clock waveform. The duty-cycle is controlled by the magnitude ratio of the...
