Problems solved by technology

[0005] The downside here is that one would worry about the complex electronics of the panel and thus be prone to failure
Also, on the downside, a separate power supply is always required to continuously power the required electronics
This disadvantage is especially noticeable in the case of equipment where power consumption affects the efficiency of the equipment, such as inverters for photovoltaic systems

Embodiment Construction

[0021] By way of introduction, it is first stated that like components in the exemplary embodiments are labeled with like numerals.

[0022] figure 1 The structure of a known inverter 1, in particular an HF inverter, is shown. Since each assembly, part and function of the inverter 1 belongs to the prior art, it will not be described in detail below.

[0023] The inverter 1 comprises at least one input DC-DC transformer 2 , an intermediate circuit 3 and an output DC / AC transformer 4 . Connected to the input DC / DC transformer 2 is a power source 12 or generator, which preferably consists of one or more solar cell assemblies 5 connected in parallel or in series. The inverter 1 and the solar cell assembly 5 can also be designated as a photovoltaic system or a PV system. The output of the inverter 1 or the output DC / DC transformer 4 can be connected to a supply network 6, such as a public or private AC network or a polyphase network, and / or to at least one consumer 7 constitutin...

Abstract

The invention relates to a method for detection of the actuation of at least one control element (16) of a control front (14) of an inverter (1) and to a control front (14) for an inverter (1) with at least one control element (16). The method essentially does not affect the efficiency of the inverter (1). The method provides that upon actuation of the at least one control element (16) at one secondary side of a transmitter (15), the transmitter will be placed under load, and the load will be detected and evaluated on one primary side of the transmitter (15) by a control apparatus (8), to which at least one actuated control element is allocated, wherein a voltage signal is applied to the primary side of the transmitter (15) and the actuation at least of one control element (16) is detected and evaluated at the voltage-free and / or unpowered secondary side of the transmitter (15) due to the change in the voltage signals at the primary side of the transmitter (15).

Description

technical field [0001] The invention relates to a method for detecting activation of at least one operating component of an inverter panel. [0002] Similarly, the invention relates to a panel for an inverter having at least one operating component. Background technique [0003] In general, it is known in the prior art to electrically insulate an operating part or a panel with a plurality of operating parts from the electronics necessary for the functioning of the device. As a result, it is necessary to ensure that the operators of the panels are not exposed to any high voltage or current and that the corresponding standards are met. The electrical isolation is often achieved in that the signals of the panel operating elements are sent via optocouplers to the control device, so that desired actions can be carried out by actuating the operating elements. However, the panel must have electronics that generate corresponding signals for the optocouplers in the case of actuatin...
