Abstract
An isolation circuit for adjustable power system in which the user analog inputs and optional user analog outputs are isolated from the load common potential by discrete value isolators instead of expensive, less accurate, analog isolators. The isolation is achieved by: digitizing the analog signal using analog to digital converter (ADC), transmitting the digital signal through a digital isolator, and converting the isolated digital data back to analog signal using digital to analog converter DAC. Discrete-value opto-couplers or isolation transformers may be used as digital isolators.
Claims20
An isolated digital controlling device for controlling adjustable module, said isolated device comprising:
- at least one user analog input line for receiving user input signal for adjusting a working parameter of the adjustable module;
- at least one analog to digital converter receiving said user analog input signal and converting said user analog input signal to digital input information;
- at least one discrete-value isolator receiving said digital input information from said analog to digital converter and transmitting an isolated digital information;
- a micro-controller adapted to receive said isolated digital information from said discrete-value isolator and produce isolated processed digital input information in response to said isolated digital input information;
- at least one digital to analog converter unit receiving said isolated processed digital input information and producing analog input signal for controlling at least one adjustable module.
An isolated digital controlling device for controlling adjustable module comprising:
- at least one user analog input line for receiving user input signal for adjusting a working parameter of adjustable module;
- at least one analog to digital converter receiving said user analog input signal and converting said user signal to digital input information;
