IPC: H02M3/155
Filed: 1987-02-18
Abstract: PURPOSE:To eliminate a constant-voltage circuit by limiting the maximum pulse width of a driving pulse of a switching transistor by a frequency dividing pulse. CONSTITUTION:In a switching power source control circuit, a flip-flop 10 generates a frequency dividing pulse (double period duty: 50%) b for specifying the maximum pulse width on the basis of a triangular wave (a) output from a triangular wave generator 20. A comparator 30 generates a control pulse (d) for driving a switching transistor 40 by the wave (a) and a feedback signal (c) from the output side of a power source through a photocoupler 60. Further, an AND gate 50 generates a driving pulse (e) of the transistor 40 by the logical product of the pulse (b) and the pulse (d). Thus, even if the pulse width of the pulse (d) is widened from the pulse (b), the pulse (e) does not become the pulse width or longer of the pulse (b), and the maximum pulse width is limited by the pulse (b).

A band gap is larger than the p type GaAs active layer 103 and carriers are effectively confined in the active layer 103. The refractive index of the embedded layer is smaller than that of the resonator section. Therefore, the light is confined in the resonator section, thereby forming an effective optical waveguide channel.
