In this paper, a novel supply voltage harmonic mitigation method using a simple DVR without harmonic detection is proposed. In contrast to the conventional DVRs control methods, the proposed method realizes two independent control objectives at fundamental and harmonic frequencies without couplings, with the adoption of the proposed voltage controller with two independent inputs focusing on different...
In this paper, a simple limited current injection method is proposed for the operation of DVR under grid voltage deep sags. The proposed method considers the impact of couplings between load power factor and grid voltage sag depth to calculate the minimum injection current that can preserve satisfaction grid voltage compensation under deep sags, Accordingly, the over current tripping off problems...
Frequency multipliers are key components for high quality sinusoidal signal provision in millimeter-wave systems. Suppression of unwanted harmonics is an important challenge, for regulatory reasons, but also since unwanted harmonics can negatively impact system performance. Explicit filtering of fundamental frequency and unwanted harmonics (even interstage in cascaded multipliers), comes at the expense...
This paper presents a novel quadrupler design that adopts the proposed polyphase filter based doubler as the first stage, which generates a differential output signal for the second doubler stage. The polyphase filter based solution features a compact size, a wide bandwidth and a well balanced output. The quadrupler is implemented in a 0.13μm SiGe:C HBT process, and demonstrates a wide bandwidth of...
