“…Pulse Width Modulation is a method wherein a fixed DC input voltage is given to inverters and controlled AC output voltage is obtained by adjusting the duty cycle [23]. Output signal alternates between ON and OFF within specified period; controls power received by a device and the voltage seen by the load is directly proportional to the source voltage [24]. Pulse Width Modulation allows us to vary how much time the signal is high in an analog way [25][26].…”

“…Nevertheless, only the square wave is able to be generated without unused energy recovery. 11 For another option, a pulse width modulation output was generated by a switching half-bridge and filtered by an RC network to produce an arbitrary output waveform. In this case, high losses are invertible due to the dissipation of a large amount of energy from the resistor.…”

In this article, a dual-stage converter driving for a piezoelectric actuator based on flyback circuit was designed and implemented, which could be applied in a micro robot. A low-voltage direct current could be converted to a high-voltage alternating current through flyback circuit and direct current/alternating current circuit in low-power condition. In the direct current/direct current stage, the charging and discharging process was realized to generate a high voltage bias from a low voltage directly supplied by battery. Then, the high voltage was converted into alternating waveform by an energy recovery circuit in direct current/alternating current stage. Experiments were conducted to verify the ability of the proposed converter to drive a 100-V-input piezoelectric bimorph actuator using a prototype 108 mg (excluding printed circuit board mass), 169 (13 Â 13) mm 2 , and 500-mW converter. According to the experimental results, this converter could be used for driving piezoelectric actuator applied in micro robot.

“…Meanwhile, a piezoelectric transformer should operate close to the mechanical resonance frequency to obtain high voltage gain and efficiency. Other topologies with more components and a high step-up ratio are also suitable for driving high-voltage reactive loads; however, most efforts have focused on large-scale and high-power applications [17][18][19]. In another part of the circuit, a simple push-pull driver described in Reference [15] can generate a unipolar square wave voltage across the load without energy recovery.…”

Piezoelectric actuators are widely utilized to convert electrical energy into mechanical strain with considerable potential in micro mobile robot applications. However, the use of Pb-based Lanthanumdoped Zirconate Titanates (PZTs) leads to two difficulties in drive circuit design, namely, high voltage step-up ratio and high energy conversion efficiency. When some devices driven by piezoelectric actuators are used in emerging technologies, such as micro mobile robot, to perform special tasks, low mass, high energy density, and high conversion efficiency are strategically important. When these demands are considered, conventional drive circuits exhibit the disadvantages of being too bulky and inefficient for low mass applications. To overcome the aforementioned drawbacks, and to address the need for a piezoelectric bimorph actuator, this work proposed a high step-up ratio flyback converter cascaded with a bidirectional half-bridge stage controlled, via a pulse width modulation strategy, and a novel control method. Simulations and experiments were conducted to verify the ability of the proposed converter to drive a 100 V-input piezoelectric bimorph actuator using a prototype 108 mg (excluding printed circuit board mass), 169 (13 × 13) mm2, and 500 mW converter.
