Abstract: The present invention relates to a piezoelectric cooling control apparatus and method, which set pulse parameters based on the temperature of the heating unit of a cooling target device, and thus control piezoelectric cooling. The piezoelectric cooling control apparatus includes a temperature sensing unit for sensing temperature of a heating unit of a cooling target device. A determination unit determines whether to activate piezoelectric cooling, based on the sensed temperature of the heating unit and a temperature setting range. A setting unit is configured to, if it is determined by the determination unit to activate piezoelectric cooling, set pulse parameters based on the temperature setting range and the temperature of the heating unit. A pulse control unit generates a PWM waveform based on the set pulse parameters and outputs the PWM waveform. A piezoelectric cooling unit performs piezoelectric cooling based on the PWM waveform.
