Ford Ranger TIM Controller

From openinverter.org wiki
Jump to navigation Jump to search

The new ECU for the Ford Ranger TIM (traction inverter module) is based on the openinverter design. It uses the original TIM's power eletronics, IGBT drivers, current sensors and voltage sensors.

So most of the information for the openinverter V2 board is also relevant for the Ranger inverter.

Just started to make the "Ranger TIM" Wiki, so most of the information is at the openinverter forum Ford Ranger section
