A direct virtual power control algorithm is presented in this paper for VSC-HVDC startup. This control algorithm is based on direct power control (DPC) and expands the range of DPC. When the VSC converter AC side open circuit or the AC side current is zero, the control algorithm maintains the DPC feedback loop by introducing a virtual power, so that the DPC is able to control the AC output volt...

This paper proposes a new resonant gate driver circuit for a soft switching synchronous buck converter in a fixed load condition. The switching energy can be fully recovered during current commutation phase in the gate driver while the diode conduction losses in the low and high side switches can be substantially reduced by employing additional L and C resonant in the circuit. Using PSpice simu...

This paper presents the electrical and thermal analysis of an OLED module. The OLED module consists of the OLED element and the DC-DC converter incorporated in its backplane. The DC-DC converter is realized as an integrated circuit and uses an external inductor. The inductor is embedded in the substrate of the backplane and has a spiral geometry. The DC-DC converter is highly efficient, but a f...

A CMOS analog to digital converter based on the folding and interpolating technique is presented. This technique is successfully applied in bipolar A/D converters and now also becomes available in CMOS technology. The analog bandwidth of the A/D converter is increased by using a transresistance amplifier at the outputs of the folding amplifiers and, due to careful circuit design, the comparator...
