High voltage modular inverter and control system thereof










Image Number 3 for United States Patent #4674024.

Low voltage GTO inverter modules are combined to form a high-voltage multi-inverter system by connecting standard modules in a string with isolated DC links. Modular construction is arranged for building multiphase systems. Voltage control is effected by controlling selected modules on the DC sides, or by pulse-width modulation of the inverter of a selected module.
