Current consumption reduction circuit for electronic device stand-by

摘要

The circuit has a periodic pulsing of the voltage in the primary or secondary circuit of a power supply building block. The recognition of the operating conditions follows from the measurement of the current consumption in order to match the energy demand to the relevant operating condition by a pulse width control system. The circuit has an electronic zero point switch (1) which is controlled by a clock generator (2) through an evaluator circuit (3) in a series circuit with a measuring device (4) lying in front of the network- side input of the power supply building block.
