20080298108 | COMPONENT CONSTRUCTION WITH SWITCHING POWER SUPPLY ACTUATES MODULE AND APPLICATION CONCEPT - A component construction with switching power supply actuates module use for stabilize voltage on/off to achieve high efficiency energy saving. With the remains of resonance electric wave form drive by vibration to make it not follow the voltage input and the changes of the electric wave load effect to stabilize voltage. In the meanwhile, when improve the electric wave form it can solve and reduce to the minimum of the high frequency harmonic wave for radiation between space. Using monitor control circuit, compare over voltage and under voltage for reference to command the voltage input and output during the current changing process and make sure the circuit power output and the electric wave are sine wave. There will be more perfect sine power driving appear on the new model module to achieve saving energy. The new module design in light weight and compact size, aside from high efficiency energy saving, it also use in both commercial and residential with changing AC to DC, AC to AC and DC to AC functions can use in different kinds of industrial and household appliance. Especially in computer, acoustic equipment, electric lamp, air conditioner, motor, elevator, arm rest elevator, electric heating water boiler and electric appliance power plug-in outlet. This module will have great potential in the future market. | 12-04-2008 |
