6 FAQs about [High voltage switch repeatedly stores energy]

What is a high-voltage MEMS plasma switch?

A high-voltage MEMS plasma switch is developed to control a buck converter transferring the energy between the buffer and the final reservoir. The switch control law is provided with an automatic narrow hysteresis loop, in order to hold the voltage across the buffer capacitor always oscillating between two high voltage levels.

How do you store electrical energy in a low-voltage circuit?

To store the generated electrical energy in order to power low-voltage electronics, a specific conditioning circuit should include an AC-to-DC converter and a DC stabilization module. Basic conditioning strategies are based on full-wave (FW) or half-wave (HW) diode-bridge rectifiers, which charge a large capacitor to a DC voltage.

Can autonomous switches improve energy management for low-voltage applications?

However, efficient energy management of the generated high-voltage for practical low-voltage applications is still under investigation. Autonomous switches are key elements for improving the harvested energy per mechanical cycle, but they are complicated to implement at such voltages higher than several hundreds of volts.

What causes a voltage ripple in a boost converter?

The output voltage ripple (ΔVout) is mainly due to the inductor current ripple (ΔIL) charging and discharging the output capacitor during the switching cycle. In a boost converter, the inductor current ripple (ΔIL) flows through the output capacitor during the off-time of the switch (tOFF), when the diode is conducting.

Which circuit has the highest charging rate and maximum harvested energy?

The highest charging rate and maximum harvested energy per cycle (11.3 μJ/cycle or 56.5 μW/5 [email protected] V) are obtained with the 2-stage conditioning circuit and the 6 µm-movable switch due to the highest switch-ON voltage as indicated in Fig. 4e.

What is the efficiency of buck converter with MEMS plasma switch?

The energy harvesting and transfer flow of the system is shown in Fig. 5e. The efficiency of the Buck converter with the MEMS plasma switch is 35%. The energy losses can be attributed to the power consumptions of the capacitor/inductor/diode leakage and the switching dissipation.
