摘要
Abstract
395B shovel DC-BUS overvoltage or undervoltage faults include that energy feedback circuit, not normal rectification and regeneration of partially controlled silicon, problems of voltage and current feedback loop, not correct bus voltage zero volt set point, inverter LEM circuit fault, frequency converter circuit grounding, inverter circuit device damage, low inverter power supply voltage. The article elaborates the causes and resolving methods of 395B shovel DC-BUS overvoltage or undervoltage fault.关键词
