AN ELECTRICAL POWER GENERATION UNIT

摘要

The invention provides a method of providing a substantially stable supply of electrical energy under loading conditions. The method includes the steps of: 1) connecting a first generator connectably with a drive shaft of a drive means; 2) connecting a second generator to the drive shaft; 3) electrically connecting the first generator to the second generator such that, in use, substantially all the electrical energy generatable by the first generator energises field coils of the second generator. The invention further provides an electrical power generation unit for carrying out the method. Yet further, the invention provides a portable welding unit including the electrical power generation unit of the invention.
