Title:
POWER CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/093425
Kind Code:
A3
Abstract:
The invention relates to a power control device for a plurality of independently operable loads (2a,2b) of a two-phase alternating current lighting network, said power control device comprising a preferably common control arrangement (3) and separate power circuit arrangements (1a,1b) for the independently operable loads. The power circuit arrangements (1a,1b) each comprise power semiconductors (1a1,1b1), an actuation circuit (1a2,1b2), which is formed as a driver circuit (1a2,1b2) controlling the power semiconductors (1a2,1b2) in a conductive or non-conductive manner, and an associated power supply circuit. The control arrangement (3) comprises a power supply circuit (3a), wherein the power supply circuits (1a3,1b3,3a) have separate reference potentials for the power circuit arrangements (1a,1b) and the control arrangement (3), and specifically in such a way that the reference potentials for the power supply units of the power circuit arrangements or power supply circuits are derived from a first lighting network phase, and that the reference potential for the power supply circuit of the control arrangement (3) is derived from the second lighting network phase, wherein the reference potential for the power supply circuit (3a) of the control arrangement (3) differs in each case from the potential point of the power semiconductors. An optocoupler (4a,4b) or a transformer is in each case provided for the transmission of actuation signals from the control arrangement (3) to the actuation circuits (1a2,1b2) between the control arrangement (3) and the actuation circuits.
