3. Cold-Start Circuit To ensure the effective operation of the power management unit (PMU), a cold-start circuit is required in the energy harvesting system to generate an initial clock signal at ultra-low input voltages. As shown in Figure 9, the designed energy harvesting system collects and converts external energy into electrical energy.
In low-power scenarios, such as microwaves, sound, friction, and pressure, a specific low-power energy harvesting system is required. Due to the absence of an external power supply in such systems, cold-start circuits play a crucial role in igniting the low-power energy harvesting system, ensuring a reliable start-up from the initial state.
An optimized cold-start circuit should exhibit high conversion efficiency to minimize wasted power, thereby extending battery life and reducing energy costs. Furthermore, the dynamic range of the cold-start circuit needs to be sufficiently wide to account for inevitable variations in voltage and power.
Furthermore, the dynamic range of the cold-start circuit needs to be sufficiently wide to account for inevitable variations in voltage and power. The most critical aspect is the anti-interference capability, which is used as the key parameter for evaluating the stability and reliability of the cold-start procedure.
The constant power cold start strategy is highly effective in reducing startup time, allowing the fuel cell to quickly reach stable power. This strategy plays an important role in applications requiring rapid startup. Additionally, it enhances system stability, ensuring reliable operation of PEMFCs.
Cold-start circuits serve to bootstrap conversion circuits when voltage levels fall below minimum levels. In these circuits, low-input-voltage levels are sufficient to drive an oscillator that, in turn, drives the switches of a start-up switched-boost converter that sacrifices efficiency for the ability to operate at low voltage levels.
