A CONTROLLER FOR A VOLTAGE CONVERTER

摘要

The present invention relates to a control module (1) for a voltage converter (3). The control module (1) has an input for connection to an AC supply (5) having an operating voltage range. A first detector (19) is provided for detecting the operating voltage range of the AC supply (5) and generating a first control signal (S1) to identify the detected operating voltage range. A second detector (21) is also provided for detecting the operating voltage range of the AC supply (5) and generating a second control signal (S2) to identify the detected operating voltage range. The control module (1) has one or more switches (39, 59) for selectively enabling and/or disabling a voltage multiplier (17) in response to said first and second control signals (S1, S2). The present invention also relates to a method of controlling a voltage converter (3).
