Direct voltage supply circuit has drive circuit threshold stage that specifies threshold voltage below which through-connection of output stage switching stage takes place to charge smoothing element
Direct voltage supply circuit has drive circuit threshold stage that specifies threshold voltage below which through-connection of output stage switching stage takes place to charge smoothing element
The direct voltage supply circuit has a rectifier circuit (1) for rectifying an input alternating voltage, a drive circuit (2) and an output stage (3) with a smoothing element (3.2) from whose output the direct supply voltage can be taken. The drive circuit has a threshold stage (2.1) that specifies a threshold value below which the through-connection of a switching stage (3.1) in the output stage takes place to charge the smoothing element.
