Control device and method for dc-dc converter

摘要

The voltage of 36-V battery (10) is dropped by the DC-DC converter (12) to charge the 12-V battery (14). The switching ON/OFF of the DC-DC converter (12) is feed forward controlled by the controlling portion (20). This can cope with the voltage change at the 36-V battery (10). The output voltage of the DC-DC converter (12) is feed back controlled by a differential amplifier (16) and PID (18) and feed back by the controlling portion (20).
