The Pulse Width Modulation (PWM) rectifier
control system on the hybrid trains developed by UGM
together with PT INKA works by relying on control from
the Hybrid Control Unit (HCU). Interconnection between
the HCU and PWM rectifier utilizes the Controller Area
Network (CAN) communication protocol. The CAN protocol
design needs to consider the conditions of the system that will
implement this communication protocol, so as to establish the
CAN standard to be used. In practice, the selection of the
CAN specification can affect the place or destination where
the CAN communication protocol is applied. Implementation
of communication between the PWM rectifier system and
the HCU must comply with existing communication protocol
standards, thus achieving stable performance. The purpose
of this study was to design a CAN communication protocol
system according to the control needs of the PWM rectifier,
which includes CAN standards, CAN baud rates, message
periods, and message frame formats. The success of the
design was tested through experimentation and validation.
Results showed that data can be sent in real time using a
20-meter STP cable. The test results desain protocol CAN
showed a delay error of 0.5% for a baud rate of 250 kbps and
1% for a baud rate of 500 kbps. According to calculations,
the CAN bus has a bus load of 0.2%, minimizing errors on
the bus. The CAN protocol was tested using CAN bus analysis
and no data frame errors were found on the CAN bus, even
in interference-intensive environments such as cables with a
voltage of 600 VDC cable in 500 watts. All tests showed that
the CAN communication protocol can function properly.
