- Figure 1. Establishing galvanic isolation with the help of optocouplers between circuits that operate at different ground potentials looks deceptively simple. Optocouplers draw power from the isolated circuit, and switching can be relatively slow and uncertain beca
- Figure 2. This circuit overcomes problems of excessive power consumption, uncertain switching, and LED aging
- Figure 3. Another variant of this design shows how to manage without a requirement for minimal reverse current in D1
