Multichannel current source having series and shunt dimming switch in each channel

Multichannel current source having series and shunt dimming switch in each channel

The current source (47) has outputs (CH1, CH2) providing constant currents (I1, I2) for operating electrical loads (10, 20). A dimming device (3) is provided for the outputs to conduct part of currents (I1', I2') flowing to the outputs to a reference potential (GND). The dimming device has...

description The current source (47) has outputs (CH1, CH2) providing constant currents (I1, I2) for operating electrical loads (10, 20). A dimming device (3) is provided for the outputs to conduct part of currents (I1', I2') flowing to the outputs to a reference potential (GND). The dimming device has switches (17, 27) controlled by a set of PWM signals (short1, short2). Another dimming device (4) has switches (12, 22) controlled by another set of PWM signals (open1, open2). A control unit controls the switches based on dimming position, and a current regulator is connected with a current modulator (1).
