DC-DC CONVERTER CONTROL [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (E))]
id0140u1004300
Without Mazda M Hybrid
Outline
• Stability of the power supply to the cabin has been realized by preventing decreases in the power supply due to battery voltage decreases while the engine is restarted by the i-stop control.
• When the engine is restarted by the i-stop control, the PCM sends a battery voltage (DC-DC converter downstream voltage) boost request signal to the DC-DC converter.

Operation
• When the engine is restarted by the i-stop control, the PCM sends a voltage boost request signal to the DC-DC converter so that the DC-DC converter downstream voltage is maintained at 11.5―12.5 V.
