2-3 Introduction on function of main module 2-3-1 Rectifier / battery charger (1) Rectifier / battery charger module is using SCR components for transforming AC to DC voltage and to recharge the batteries. (2) In Rectifier / battery charger module, double control method to CPLD and DSP are combined to keep rectifier and battery charger more steady and reliable. (3) Has complete system for protection from over voltage. (4) Detection on phase sequence error or single phasing.
2-3-2 Introduction to inverter module (1) Uses IGBT as power component. (2) Uses high technology DSP to control the inverter module. (3) Utilize digital control management to prevent discrete component from aging, temperature slant and reduce the quantity of parts to enhance system reliability. (4) Integrated A/D signal processing, 12bit resolution and high speed transferring capability.
2-3-4 Input start up/protect trigger (1) Start up function. This function is used for delaying the input power during start up or utility recovery to protect the unit from electrical surge impact. The function is controlled by the main control board. (2) Protection function. This function is used whenever input voltage is too high or too low or wrong phase sequence or if one phase is missing. In this case, the input trigger will be cut to protect the unit.
