The present application relates to the technical field of field bus communication, and in particular to a protocol converter between a CPCI bus and an ISA bus and a conversion method thereof, which are suitable for communication between railway vehicle CPUs and vehicle bus MVB devices. The protocol converter comprises a CPCI local bus interface extension timing module, an ISA bus interface timing module, a CPCI bus matching ISA bus timing interface module, and a clock management module. The CPCI bus realizes communication with the ISA bus by the protocol converter. The traditional conversion bridge chips are replaced with the protocol converters without changing the traction controller structure and other devices in the system; the flexibility is high; and the functions are diverse. In addition, 8-bit data width or 16-bit data width of the ISA bus is supported, and the operation of an ISA bus device by a CPCI bus device in the form of IO or in the form of MEMORY is supported.
