Development of EM7000is Dual-voltage Inverter Generator

Article of Honda R&D Technical Review Vol.16 No.2


Honda’s current inverter generators have a maximum power of 3kVA and single-voltage output. Dual-voltage output is essential when producing higher-power inverter generators, because the larger equipment connected to them requires either high current or high voltage. A new dual-voltage inverter has therefore been developed. The dual-voltage inverter produces two voltages by connecting two inverters in parallel or in series. Sub-winding for the inverter unit power supply has not been employed in the alternator. Only main winding has been used, and power supplies have been built into each unit, meaning that the system is composed of the output of the main winding. This has enabled the alternator to be reduced in size and increased in efficiency. The completed generator is fitted with an integrated control unit. The centralization of control functions has enabled 2/3 of the electronic components to be eliminated and a liquid crystal monitor to be employed to display information. Like Honda’s previous inverter generators, the newly developed EM7000is employs an electric governor. In combination with its shroud sound isolation duct structure, this enables the unit to run quietly with high fuel efficiency.
