Abstract: A circuit used to convert DC input to AC output comprises a transformer and three series sub-circuits. The first series sub-circuit is connected in parallel with the DC input and comprises first and second capacitors connected in series. The secondary series sub-circuit is connected in parallel with the DC input and comprises a first primary winding of the transformer, a clamping capacitor and a second primary winding of the transformer sequentially connected in series. The third series sub-circuit connected in parallel with said clamping capacitor and comprises first and second switches connected in series. The center nodes of the first and third series sub-circuits are connected together. Thus, while a secondary winding of the transformer provides AC voltage, the circuit is able to effectively reduce current ripple and decrease voltage stress on semiconductor switch with minimum component count. Similar topologies may be used for rectification instead of inversion.

Abstract: A liquid crystal display device is disclosed, which comprises an upper substrate, a lower substrate, and a liquid crystal layer. The lower substrate has several pixel electrodes, metal lines, and switch elements thereon. Each switch element comprises a source electrode, a drain electrode, a gate electrode, and an opening between the source electrode and the drain electrode. A passivation layer covering the surface of the source electrode and the drain electrode forms two inclined planes separately on two sides. The two inclined planes face each other and are locating on a kink or step of the source electrode and drain electrode. The inclined planes also contact each other at the upper side of the opening. The inclinations of the inclined planes to the lower substrate are in a range from 5 to 50 degrees.

Abstract: A logic device with low electromagnetic interference. The logic device includes a digital logic gate, a voltage-limited circuit and a current-limited circuit. The digital logic gate provides a corresponding digital logic function. The voltage-limited circuit is connected to the digital logic gate in order to provide a fixed voltage to the digital logic gate to thus reduce an output voltage swing of the digital logic gate. The current-limited circuit is connected to the digital logic gate in order to provide a fixed current to the digital logic gate to thus reduce a transient current of the digital logic gate. Accordingly, an electromagnetic interface (EMI) caused by switching of the digital logic gate is reduced with the reduced output voltage swing and transient current.
