该论文提出了一种去中心化菊花链控制的开关电容驱动器，用于微机器人静电和压电致动器的高压驱动（100-300V）。该驱动器解决了传统方案中体积大、重量重、无功功率损耗高的问题，实现了10倍的功率降低。
Electrostatic and piezoelectric actuators are used in a number of mm- and cm-scale robotic applications due to their relatively high energy-density at small size and weight [1-3]. Such transducers typically require high drive voltages (100 to 300V) at relatively low frequencies (<1kHz) where they present as dominantly capacitive loads (1’s to 10’s of nF). Challenges associated with the drive circuits for these devices include: 1) a need to generate a high-voltage drive waveform, often boosted from a low-voltage supply; 2) extreme size (<1 cm2) and weight (<<1g) constraints; 3) reactive power (CloadVOUT,pp2fsw) is typically much higher than real power, i.e., mechanical work done by the actuator [4,5]; 4) solutions often require primary (non-rechargeable) batteries which can source but not sink power. Thus, the ideal actuator driver would supply reactive power efficiently, boosting from a low-voltage supply, but also recover this energy during
