Input Circuit for a Switch-Mode Power Supply |
摘要 |
The invention relates to an input circuit for a logic circuit part, comprising a voltage converter component for conversion of a mains voltage to the required low voltage in order to supply a user with a low voltage. The supply to the input circuit may hence be connected to a mains supply to rectify the mains voltage and an output from the input circuit may be connected to the voltage converter component to provide a rectified input voltage for the voltage converter component. According to the invention, an improved input circuit for a logic circuit part with improved functionality and operating security also permitting an extensive miniaturization and simplified production may be achieved by replacement of at least two of the remaining four diodes in the rectifier part of an input circuit for a logic circuit part by two controllable switches which work as a synchronous rectifier and are connected such as to be switched on and off by alternate forced control.
