4. Products Introduction

4.1 Topology Description
PIC2 shows the whole HUMMER-20KW system including, inverter, unloader and wind
turbine. The wind generator will convert wind power into AC, which will be converted
into DC by the unloader; the inverter will convert DC into sustained AC to charge the
grid at last. With the advanced technology of IGBT and control processor,
HUMMER-20KW can work with higher power and charge voltage.
