Abstract

PURPOSE: To convert a battery power to three-phase alternating current in high reliability by providing 12-bit shift register operating with an oscillator and connecting the output of the shift register through a semconductor switching element to an output terminal.
CONSTITUTION: A rectangular pulse from an oscillator O is applied as shift pulse to 12-bit shift registers IC2∼IC4, and the output of the shift register IC3 is fed back through a NOR gate IC5 to the DATA 1 of the shift register IC2. There are also provided a switching element Tr8 connecting the output terminal R to ground when the output Q1 of the register IC2 is "high", a switching element Tr7 connecting the output terminal R to a DC power supply when the output Q7 of the register IC3 is "high", at the terminals S and T, respectively. Thus, the switching elements are driven on the basis of the output of the shift registers. Accordingly, it provides always constant phase difference to operate extremely accurately.
