Description

technical field [0001] The invention relates to the field of multi-mode power converters, in particular to a field-use multi-mode power converter and a control method. Background technique [0002] Due to the different power environments in various regions of the world, there are generally differences in the AC voltages and corresponding frequencies used, resulting in inconsistent voltage / frequency ranges for electrical appliances in various countries. China, Israel, Australia and other countries use 220V / 50Hz single-phase AC power, the United Kingdom, France, Germany and Italy use 230V / 50Hz power supply, and the United States and Japan use 100~120V power supply. The frequencies are 50Hz and 60Hz respectively. In recent years, with the rapid development of power electronics technology and the continuous acceleration of the global economic integration process, it often occurs that due to different power supply systems, the equipment used cannot be used in countries other tha...
