<p>PURPOSE:To convert each duty wave form of output from a pair of switching elements to 50% duty, by providing a saturable reactor and a pair of switching elements to a magnetic multiplex circuit. CONSTITUTION:In a magnetic multiplex circuit 4, when the winding number of a secondary and a third coils 44, 45 are set to each (n), the voltage applied to the secondary and the third coils 44, 45 are set to each Ec and the saturation magnetic flux of a saturable reactor 41 is set to phim, the circuit 4 is always oscillated at a definite cycle T as shown by the formula T=4.n.phim/Ec and transistors (Tr) 46, 47 as the switching elements of the multiplex circuit 42 are mutually electrically connected within this cycle T. When currents flowing through lines 31, 32 are equilibrium, voltages induced in the secondary and the third coils 4, 45 by the lines 31, 32 are zero. Therefore, the duty ratio of the electrical connection and the cut-off of Tr 46, 47 is brought to about 50%.</p> |
