Abstract
PURPOSE: To convert a battery power to three-phase alternating current in high reliability by providing a flip-flop which is set or reset by the output of a duodenary counter and connecting it through a switching element to an output terminal.
CONSTITUTION: This power supply consists of a duodenary counter CO for sequentially generating outputs at twelve output terminals via a clock pulses, six sets of flip-flops IC5∼IC10 set or reset by the output of the counter CO, a switching element Tr7 connected to the output terminal R with a DC power supply when the flip-flop IC5 is set, and a switching element Tr8 connected at the output terminal R to ground when the flip-flop IC6 is set, at the respective terminals S and T, respectively. Since the phase difference among the respective phases can be extremely accurately obtained, it can operate exactly with high reliability.
