15KW PCS energy storage converter AC/DC bidirectional power module

Function Description:

• More secure and reliable:

  Full high-frequency isolation design ensures the safety between the battery and the grid/load;
  Full digital control of DSP + CPLD, with multiple levels of software and hardware overcurrent, overvoltage, and over-temperature protection, ensuring safety and reliability;
  Dual DSP design, with stable and reliable performance;
  Reliable parallel connection function, facilitating power expansion, allowing up to 12 modules to be connected in parallel;

• Higher efficiency:

  Compared to traditional bidirectional power supply solutions, it eliminates the line-frequency transformer, achieving higher high-frequency isolation efficiency, reaching over 95%;
  AC/DC adopts three-level technology, with a maximum efficiency of 98%;
  DC/DC adopts soft-switching resonant technology, with a maximum efficiency of 98%.

• More intelligent and user-friendly:

  Equipped with an STS module, supporting seamless switching between grid-connected and off-grid modes;
  Covers multiple battery voltage levels for passenger vehicles (100V~750Vdc), with a wide battery voltage range;
  Wide grid voltage range and adaptive capability for 50/60Hz voltage frequency.

• Lower cost:

  Compared to traditional bidirectional power supply solutions, high-frequency isolation eliminates the line-frequency isolation transformer, resulting in lower system cost;
  By using a single circuit to achieve both charging and inverting functions, with integrated charging and discharging, the cost is low;

• More flexible configuration:

  Supports 19-inch standard rack installation, with a compact structure;
  Module hot-swappable design, allowing flexible system configuration;
  Facilitates system integrators to flexibly design different forms of energy storage or battery-to-grid systems.
