We are into the manufacturing of hopper heaters; these can be availed by our customers easily at affordable prices. Ferrite core based high frequency transformer rectifier (HFTR) unit is a high voltage switch mode power supply (SMPS) unit for electro static precipitator (ESP). It suppes a smooth and ripple free high voltage DC into the esp. field using the small internal capacitance of the fields. It improves the efficiency of esp. and the conventional thyristor controlled set. The HFis powered by a micro-controller based on IGBT controlled panel. The supply voltage of the panel is 3 phase 415 V 50/60 Hz.As it can be seen in the Schematic diagram: fine particles emissions are much more dangerous to health than the larger ones. Collecting of fine particles below 10 micro meters (pm10) in electro-static Precipitators has not been very efficient with conventional system. A new high frequency set was developed with a pulse duration of below 50 micro-second to use it with existing Precipitators. Current capabity had to be in the KA range. It is possible to generate a high charge density in the electrode area, which results in increase charging of the fine particles. Flash ove sparks are mainly avoided due to the short pulse duration. Data can be recorded on a real time precipitation in any ESP.
