  1. Off-the-Shelf Watchdog Serves in a Pinch
    The performance of the watchdog circuit in Figure 1 may not match that of a dedicated watchdog circuit, but this circuit is helpful when the only watchdog in the lab doesn’t meet your design’s...
  2. Use a Current Mirror to Control a Power Supply
    Controlling a power supply is a necessary task in many applications, such as in battery chargers, solar power controllers, and so on. Industry provides a rich number of off-the-shelf integrated power supplies that,...
  3. Achieve MPPT Control Without Power Calculation
    A maximum power point tracking (MPPT) controller circuit is extremely useful in solar photovoltaic systems for boosting power usage efficiency. The traditional MPPT design, though, requires the use of a multiplier to...
  4. "Unstable" Power Supply Simulates Solar Panel Behavior
    Giovanni Romeo Giuseppe Urbini
    This power supply may seem a bit strange, since it’s not stable in voltage or in current. However, it simulates the behavior of a solar panel and can be very useful if you’re working with a solar-powered...
  5. Supervisor Circuit Decides When Solar Array Can Power A Load
    The performance of solar-powered electronic devices may suffer in twilight conditions. In particular, microprocessors often used to perform solar power conditioning (such as in maximum-power-point trackers) do not like...
