Epic Power Converters » Products » Bidirectional DC/DC Converters Bidirectional DC/DC Converters Bidirectional high-efficient DC/DC power converters. With a wide range of voltage levels in both sides, the EPCs are capable of managing power in both directions. Features DC DC converter Why a bidirectional DC/DC Converter? EPC systems have shaped the new generation of bidirectional DC/DC Converters. EPCs (Epic Power Converters) are suitable for a large number of applications ranging from industrial ones to those in the field of renewable energies. Bidirectionality Managing energy flow in both directions Ultra-high efficiency achieved with silicon carbide transistor technology. Scalability Scalable with easy paralellization. Galvanic isolation of the entire structure Maintains the DC link voltage in the absence of main supply. Soft pre-charge of the DC link Suitable to switch ON and OFF the drive as many times as required in order to save energy and life expectancy of the inverter. Automatic change of power flow to stabilize either input or output voltage without stopping voltage regulation. CAN communication available to implement voltage or current control and transmit relevant measurements of operation parameters (voltage, power, current, temperatures, etc.). Customized versions available upon request. Request here As a typical application the low side voltage can be connected to batteries or ultracapacitors to feed any drive (VVVF) directly through the DC link. This allows the system to continue in operation in case of lack of mains supply. It also allows for off-grid applications where there is no three-phase mains available or, for example, in automatic warehouses when the platforms are moving off-grid. Product range Isolated bidirectional DC/DC converters Isolation implies a galvanic separation between the ports, which means there is no direct current path between them.
