~ CD Automation’s new power-line filters reduce energy losses ~ CD Automation, a UK manufacturer and supplier of industrial automation, controllers and drives has launched the UK photovoltaic industry’s first family of DC power line filter solutions supporting 1500V panels. The new filters maximise the operating DC voltage to the limit of the European Union’s Low Voltage Directive (LVD). The inverter filters allows for both single- and multi-stage performance options, to mitigate electromagnetic interference (EMI) scenarios. Their high voltage means they have lower current, thereby minimising cost by decreasing losses from heat dissipation. “The photovoltaic infrastructure cost savings that results from moving to higher DC voltage and lower current are very compelling,” explained Jez Watson, managing director of CD Automation UK. “The main benefit to our customers consists in the lower costs of DC power components while delivering higher inverter power density and efficiency.” The products are ideal for inverter manufacturers seeking field-proven power line filters designed specifically for this task. The two types of EMI Inverter filters – the RP300 series of AC Inverter filters suitable for wind turbines, and the RP600 series of DC filters – are designed for the photovoltaic inverter industry. The DC filter is installed between the solar photovoltaic panel and the inverter, thus helping to control conducted emissions on the panel side of the system and therefore significantly reducing the potential for high-frequency (HF) interference radiation off the panel. The filter also protects the solar panel from HF stray and leakage currents which can cause premature aging in the photovoltaic modules.
