    摘要: A power converter comprising a current-type inverter is disclosed, in which an output of a converter unit is applied as an input to the inverter unit through a DC reactor, and AC power is supplied to a load from the inverter unit. A ripple component of the DC input of the inverter unit is detected, and the switching elements of the inverter unit are controlled by modulation rate if they are to be subjected to PWM control, thus completing a sinusoidal waveform of the output of the inverter unit. Specifically, since the input to the inverter unit is allowed to contain a ripple, the DC reactor is reduced in size. The output of the inverter unit is a sinusoidal AC power containing no high harmonics and therefore the load is free of effects of high harmonics.

    摘要: When a microprocessor fetches an instruction to be processed by a coprocessor, it sends to the coprocessor a command corresponding to the instruction while informing the coprocessor that the bus cycle is in the mode of transfer of the instruction to the coprocessor. In transferring an operand from the memory to the coprocessor, the microprocessor asserts, in addition to a usual memory read signal, a signal (CYCYCL) indicative of validity of the coprocessor and instructs the coprocessor to fetch data to thereby complete the operand transfer from memory to coprocessor within one bus cycle. In transferring data from the coprocessor to the memory, the microprocessor asserts, in addition to a usual memory write signal, the CYCYCL signal and instructs the coprocessor to deliver the data to thereby complete the data transfer from memory to coprocessor within one bus cycle. Thus, the signal transfer between memory and coprocessor can be completed within one bus cycle without resort to the provision of duplicate hardware in the coprocessor.
