High frequency (500KHZ or more) SMPS power converter manufacturing technology

摘要

The present invention (design) is to reduce the size and weight of the 40KHZ switching mode power supply (abbreviated SMPS) of the conventional PWM method more and save its own power consumption (10-30% increase in efficiency) We have successfully invented a new SMPS circuit to fabricate this SMPS by increasing the switching frequency to over 500KHZ.;The key technology of the new SMPS device is that the power supply line of the conventional SMPS circuit is separated into two power supplies as shown in FIG. therefore The pole power line should be supplied separately from the driver of the system and the main DC TO AC converter. It must also be separated from the output circuit.;This device is widely used as a basic power supply device for electronic and information equipment such as TV and computer which are widely used at present, and is widely used as lighting device of central fluorescent lamp and widely used in lighting equipment of offices and homes, and as a driving device of servo motor. This will have a profound impact on the national economy in terms of energy saving.
