Abstract: A selenization/sulfurization process apparatus for use with a single-piece glass substrate is characterized by two chambers for heating up a glass substrate quickly and performing selenization/sulfurization on the glass substrate to not only prevent the glass substrate from staying at a soaking temperature of a softening point for a long period of time but also increase the thin-film selenization/sulfurization temperature according to the needs of the process to thereby reduce the duration of soaking selenization/sulfurization, save energy, and save time. The glass substrate undergoes reciprocating motion in the chambers to not only attain uniform temperature throughout the glass substrate but also distribute a selenization/sulfurization gas across the glass substrate uniformly during the selenization/sulfurization operation. The recycled liquid selenium/sulfur and inert gas are reusable to thereby reduce material costs.

The processing unit obtains the duty ratio according to the inductance of the inductor, the total variation of the inductor current, the DC voltage and the output voltage.

Abstract: Current of a three-phase multilevel modular converter (MMC) is controlled. The control is a division-summation (D-?) method yet uses integration to replace the two steps of division and summation. Common D-? characteristic equations are used for all areas. Inductance changes are considered in the characteristic equations. Current source is used to control converter. Therefore, the current of the converter can be traced to sinusoidal reference current even when the inductance changes become big. The modulation method and the capacitor-voltage balancing method are submodule unified pulse width modulation (SUPWM) and sorted voltage-balancing method, respectively. The current control directly obtains a law of the current change on each conducting module of an arm. It does not need complex sector judgments and table look-ups. Thus, the amount of computation and memory for a processor can be relatively reduced.

Abstract: A method is provided for current compensation. The method is based on division-sigma (D-?) control for a DC/DC converter. Inductance changes are allowed with D-? digital control achieved. Loop gain can be quickly adjusted. The disadvantage of average current-mode control (ACMC) is solved, where the disadvantage is a reduction of the response speed caused by the filter within the current loop. The present invention uses midpoint current sampling to ensure taking an average inductor current value in each switching cycle. By doing so, a lack of fidelity of peak current-mode control (PCMC) is solved, where the lack of fidelity is due to the amount of error value between the peak value and the average value. Besides, the present invention uses a table of the inductance following current changes to achieve compensation of duty cycle ratio, where the table is built in a single chip.
