The ability of a piezoelectric actuator in energy conversion is rapidly expanding in several applications. Some of these applications for which an ultrasound piezoelectric actuator can be used are surface cleaning, metal cutting and welding, and biomedical applications such as needleless drug delivery. A new application of piezoelectric actuators is the Avionic Deicing System. The working frequency of actuator is between 100 kHz and 150 kHz, depending on temperature and ice thickness, and output power levels at several hundreds of Watts. The power supply of piezoelectric actuators has to provide an output voltage of up to 200 VAC at the resonance frequency with low consumption. This article discusses and analyzes a low-consumption electromechanical deicing solution based on piezoelectric actuators, its operating principle, and its driving power supply development supported by experimentations on the setup representative of a part of the Nacelle.

AbstrakPhotovoltaic merupakan sumber energi terbarukan yang banyak dikembangkan, namun output dari photovoltaic masih dalam bentuk arus searah (DC). Oleh karena itu, diperlukan perangkat yang bisa mengubah tegangan DC menjadi tegangan arus bolak balik (AC). E class zero-voltage-switching resonant inverter sebagai salah satu konverter DC ke AC akan diimplementasikan. Rangkaian E class zero-voltage-switching resonant inverter dikontrol melalui sinyal analog PWM yang dibangkitkan IC SG3524. Penggunaan ZVS (Zero Voltage Switcing) memiliki tujuan untuk mengurangi kerugian tegangan pada proses switching MOSFET. Rangkaian resonan π1b dirancang dan digunakan untuk memperbaiki bentuk gelombang keluaran dan meningkatkan tegangan keluaran inverter. Percobaan dilakukan dengan variasi beban, duty cycle, dan frekuensi untuk menyelidiki respon E class zero-voltage-switching π1b resonant inverter. Beban berupa lampu pijar 15W, lampu pijar 25W, dan motor induksi satu fasa capacitor run. Dari hasil uji tegangan keluaran didapatkan bahwa nilai tegangan keluaran meningkat dari frekuensi 49Hz ke 50Hz, kemudian nilai tegangan keluaran menurun dari frekuensi 50Hz ke 51Hz. Pada variasi duty cycle, tegangan output meningkat dari duty cycle 10% ke 50% dan kemudian tegangan output menurun dari duty cycle 50% ke 90%. Frekuensi juga mempengaruhi kecepatan putar motor, seiring dengan meningkatnya frekuensi, kecepatan putaran motor juga meningkat. AbstractPhotovoltaic is a renewable energy source that is widely developed, however the output of photovoltaic is still in a form of direct current (DC). Therefore, a device that can convert DC voltage to alternating current (AC) voltage is needed. E class zero-voltage-switching resonant inverter as one of DC to AC converter is interested to be implemented. The use of zero-voltage-switching has a purpose to reduce the voltage losses in mosfet switching process. The π1b resonant circuit was designed and used to improved the output waveform and increased the output voltage of the inverter. The experiments were carried out by variation of load. The loads were a 15W incandescent lamp, 25W incandescent lamp, and one phase induction motor capacitor run. From the output voltage test results it was found that the output voltage value increased from the frequency of 49Hz to 50Hz, then decreased from frequency of 50Hz to 51Hz. In the duty cycle variation, the output voltage increased from the 10% to 50% and then decreased from the duty cycle 50% to 90%. Frequency also affect the motor rotation speed, as the frequency rise, the speed of motor rotation also increased.
