Liquid ejecting apparatus and liquid ejecting printing apparatus |
摘要 |
A liquid ejecting apparatus includes: a Modulator that performs pulse modulation for a drive waveform signal that becomes a reference for a drive signal of an actuator so as to acquire a modulated signal; a digital power amplifier that amplifies the power of the modulated signal so as to acquire a amplified digital signal; a low pass filter that smoothes the amplified digital signal so as to acquire the drive signal; a variable power source circuit that can change a power source voltage of the digital power amplifier; and a power source voltage control unit that controls changes in the power source voltage in units of a driving pulse that configures the drive signal of the actuator and can independently drive the actuator. |
