When the target duty ratio of an arbitrary phase (U-phase) has become an uncontrolled duty ratio (for example, 5% or lower or 95% or higher), a duty ratio correction section (5b) obtains corrected duty ratios by either adding or subtracting a differential duty ratio, that is, the difference between the target duty ratio of the arbitrary phase (U-phase) and a controllable duty ratio (for example, 0% or 100%), to or from the target duty ratios of the other phases (V-phase, W-phase). A PWM output section (5c) applies a PWM signal, which is based on the controllable duty ratio and the corrected duty ratios, to the power device (3)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Inverter device and PWM signal control method","description":"A duty ratio calculation section (5a) of this device calculates target duty ratios of respective phases on the basis of a motor current value.
