High-frequency DC to AC Inverter
The DGPN series DC to AC pure sine wave inverter is specifically designed for the practical needs of power and communication systems, It uses higher switching frequencies electronic components, resulting in a compact size, lighter weight and higher efficiency, its versatile and stable performance well integrated In communication power systems.
The DGPN series inverter is one perfect unit to supply pure sine wave ac power (THD≤3%), specifically designed for communication systems. Its core function is to convert commonly used 24V,48V,110V DC power to 220V 230V, 50Hz/60Hz AC power, to meet the AC power supply needs of communication equipment in specific scenarios. They are key equipment to ensure the flexibility and continuity of communication system power.
- Compact in size and Light in weight: the higher switching frequencies and optimal configuration design to achieve the compact and light design. ldeal for applications where space and weight are critical, such as in vehicles or portable systems.
- Higher eficiency: High-frequency inverters achieve higher conversion eficiency by reducing of switching losses, fully considered the use of more advanced semiconductor devices, which lead to lower energy consumption and lower operating costs, especially in continuous use scenarios.
- Faster response time: Due to the higher switching speeds, they can react more quickly to changes in load and voltage fuctuations.
- Complete electrical isolation between DC and AC in all circuits, to eliminate all possible interferenceCompletely protection: over voltage, overload, short circuit, over heat protection.

DC to AC High-frequency Inverter Principle Block Diagram
The DGPN power inverter receives a DC input voltage from a battery or any other DC sources. The high-frequency switching IGBTs of inverter rapidly switch the DC current on and off, creating a pulsed wave form, the pulsed waveform is then filtered to produce a smooth, sinusoidal AC output at the desired frequency (e.g., 50Hz or 60Hz).
