The present invention discloses a signal controlling technology. A triangle-wave generating device of enabling a frequency control variably and a drive method of the same are configured such that: after converting amplified sine wave into a first square wave having preset gain value, a second square wave, which is level downed peak value of the first square wave, can be converted into a triangular wave within low band - high band frequency range and peak values of rated triangular wave can be used as a comparison wave of PWM (Pulse Width Modulation), etc. by controlling an integrator which produces rated triangular wave having error range of -10% to +10% of reference peak value from a comparison of peak value of feedback triangular wave and reference peak value. |
