AC constant current source , there are two types: Linear AC constant current source and switching AC constant current source.
1. Features of linear AC constant current source:
(1) The output current is constant and can be adjusted continuously from zero to the rated value.
(2) When using a linear amplifier circuit, the output waveform is a standard sine wave with low distortion.
(3) The output current is high precision, low ripple and low noise.
(4) The power supply efficiency is high, 20% higher than the conventional linear power amplifier.
(5) The output frequency range is wide, and the output can be from DC to 10 kHz.
(6) The external analog signal can output various waveforms, such as square wave, triangle wave and sine wave.
2. Features of switching AC constant current source:
(1) The output current is constant and can be adjusted continuously from zero to the rated value.
(2) When using SPWM high frequency modulation, the output waveform is pure sine wave, and resistance, inductance and capacitance can be loaded.
(3) The output current achieves high precision, high current and fast response time.
(4) It can realize remote control with various communication interfaces of other systems.
