This paper proposes a diamond-shaped high step-up switched-capacitor based basic multilevel inverter topology. The (SC) stage consists of 2 active switches, diodes, and capacitors. Using single DC source with the unfolding circuit (10 5 capacitors, diodes) results in production 17 voltage-steps at output gain up to 8 times input voltage. By extending stages, higher voltage levels gains can be p...

A new primary side regulation constant voltage (PSR-CV) two-stage solution is proposed in this paper to avoid low frequency current ripple and to maintain high power factor, low cost compared with currently single stage and conventional three-stage solution in analog LED dimming or non-dimming application. PSR-CV is employed in primary side to achieve high power factor, simple circuit combined ...

We present a micromachined, stress-induced, thermal bimorph actuator for optical purpose. Piston motions of more than 3um are demonstrated by FEM simulation. Upon the release from the substrate, the actuators lift off the substrate due to a large built-in bending moment arising from the compressive residual stress in the poly-silicon layer and tensile residual stress in the metal layer. Large d...

ESD robustness of Low Temperature Poly-Si (LTPS) diodes and TFT devices has been investigated in this paper. By using the Transmission Line Pulsing (TLP) techniques, the It2 (secondary breakdown current) of LTPS diodes and TFT devices were measured. To evaluate the ESD robustness of components for ESD protection, the shifts of breakdown voltage and cut-in voltage of LTPS diode and TFT devices a...

Forward converters generally exhibit poor power factor when employing in the AC-DC conversion, due to the presence of zero input current near the zero crossing of line input voltage. In this paper, a single-switch forward converter with high power factor and low storage capacitor voltage stress is proposed. By adding a stack up voltage on top of the reflected input voltage on the forward conver...
