ABSTRACT:
A multiplicity of electronic devices is provided to generate triangular wave signals variable between an upper and lower limit voltages by charging or discharging capacitors. One of the triangular wave signals serves as a master triangular wave signal for controlling the phases of the remaining (or slave) triangular wave signals. A detection signal is generated every time the master triangular wave signal reaches predetermined threshold levels. In response to the detection signal, a capacitor associated with one slave triangular signal is promptly discharged to bring the slave triangular signal to the lower limit voltage, whereby the respective slave triangular wave signals are synchronized to be offset in phase relative to the master triangular wave signal by respective predetermined phase angles.
