DC Frequency Converter 380v to 220v

With the popularization of high-voltage direct current distribution in new energy power stations, data centers, ships, and advanced industrial scenarios, a core challenge has emerged: how to supply power to a large number of conventional equipment that only supports 220V AC? 

SPX's high quality DC Frequency Converter 380v to 220v is precisely the "standardized power export" designed for this purpose. It is like an efficient "power language translator", specializing in accurately translating the abundant 380V DC "native language" in the system into a 220V/50Hz AC "common language" that can be understood by various devices, allowing you to enjoy the efficient and concise advantages of the DC system while using all mature AC electrical equipment without compromise.

The SPX factory's CE-certified DC Frequency Converter 380v to 220v adopts high-frequency isolation and optimized topology, directly converting 380VDC to 220VAC. Compared with the traditional two-stage scheme of "DC-DC step-down and inverter", it reduces the conversion link, with a typical efficiency of over 94%, reduces energy loss, and improves the overall energy efficiency from the DC source to the final load.
Specially designed for the output voltage range of photovoltaic arrays or the working voltage range of battery packs, it can operate stably under a wide DC input voltage (such as 300V-450VDC), ensuring continuous and reliable power supply during power fluctuations.

Output standard pure sine wave AC power with smooth waveform and total harmonic distortion rate below 3%.
The design of DC Frequency Converter 380v to 220v considers mixed load scenarios, which can drive resistive loads (such as lighting and heating), as well as easily handle the starting impact of inductive loads such as motors and compressors (usually with a 150% overload capacity), making it widely applicable.

Application

On the 380V DC bus of a large photovoltaic power station or energy storage container, this equipment is connected to supply power to all auxiliary AC loads such as the monitoring system, lighting, air conditioning, and maintenance tools in the station, achieving self-sufficiency in electricity consumption.
In semiconductor factories, data centers, or special workshops that use 380V DC busbars, the DC Frequency Converter 380V to 220V provides independent power for specific areas or old equipment, experimental instruments, or office equipment that require 220V AC.
On ships, new energy mining trucks, and rail vehicles that use DC integrated power systems, high-voltage DC power is converted into 220V AC power required for household equipment, which is used for kitchen appliances, entertainment systems, lighting, etc.
