摘要:

The paper presents a new Class E lowdvD/dtrectifier, its analysis and experimental results. The rectifier circuit contains a capacitor connected in parallel with a rectifying diode. The capacitor sets the conduction angle of the diode current, and the output-filter capacitor independently sets the AC ripple on the DC output voltage. The diode-junction capacitance is included in the parallel capacitance and threrefore does not adversely affect circuit operation at high operating frequencies. The diode turns on and off at lowdvD/dt, yielding low switching losses and low switching noise. Moreover, the absolute value ofdiD/dtat turn-off is limited by an external circuit, significantly reducing the reverse-recovery effect. For these reasons, the rectifier is especially suitable for high-frequency operation. Basic parameters of the circuit are derived, using time-domain analysis. The experimental and theoretical results were in good agreement.
