The proven "Parallel Resonant Current Fed" topology is employed to ensure highest degree of reliability and efficiency besides ensuring Constant Power tracking in a variable impedance load as commonly encountered in an Induction Melting cycle. The result is improved load factor & maximum productivity per kVA of unity demand. The Converter houses a controlled rectifier converting fixed 50 / 60 Hz AC voltage to variable DC voltage followed by a DC Link Reactor that acts as a current source of an Inverter, which is turn converts DC to AC of desired frequency. The parallel Capacitor Bank that supplies the reactive power demand of Inductive load is either separately built or integrated within the converter housing, de-ionized water is employed to cool the Power Source by employing Plate type Heat Exchanger that separates it from the electrically conductive primary cooling water source.

With the purpose of controlling the frequent downward regulation of power, D.C Choppers are also utilized to maintain constant Mains Power Factor under all operating conditions.
