A modular-based, zero-current-switched, isolated full-bridge boost converter with multiple inputs is disclosed. The development of reversible protecting groups greatly enhances the current utility of silanes while introducing further novel applications. The marking patterns are composed of two or more independent sections, the first section is a grid representing for example, the mortar joints in a brick wall. The core circuit receives a reset signal transmitted by the reset signal line and activates a reset operation accordingly. The moving member may move the printed circuit board so that the printed circuit object passes through an internal space surrounded by the coil.
