Rancang Bangun Low Power Elektric Surgery (Pisau Bedah Listrik) pada Frekuensi 10 KHz

In this study, It is proposed a design of electric surgery on 10 KHz. This device consists of a power supply circuit, a voltage regulator, and a frequency counter. The purpose of this study is expected to minimize the occurrence of spark overs and the occurrence of burns. The measurement results show that LPES is working with a power of 26 watts and a frequency of 11.16 KHz. Electric surgery was tested against buffalo meat, mutton and beef. In beef by applying a voltage of 28.7 volts takes 51 seconds, using a voltage of 28.1 volts takes 53 seconds, using a voltage of 27.8 volts takes 57 seconds. In goat meat by using a voltage of 28.7 volts takes 30 seconds, using a voltage of 28.1 volts takes 41 seconds, using a voltage of 27.8 volts takes 49 seconds. In buffalo meat by using a voltage of 28.7 volts takes 52 seconds, using a voltage of 28.1 volts takes 56 seconds, using a voltage of 27.8 volts takes 59 seconds. Compare to another electric surgery, this study had low power and low frequency, so as to minimize the occurrence of spark over with good speed cutting process.
