Abstract
Along with the increasing development of covid-19, an innovation is needed that can be used to help deal with covid-19. SME Robotics University of Jember researched to create robot assistant nurse 19 (ASPER-19) to minimize contact with patients. This robot requires AC voltage while the input voltage used is DC voltage in carrying out its performance. Therefore, changing the voltage from DC to AC using an inserter tool. In this study, the inverter utilizes the EGS002 module as an SPWM driver in the switching process uses four pieces of MOSFET with hy4008 type arranged on an h-bridge basis. To increase the voltage to 220VAC utilizing a kind of low-frequency transformer. The low-frequency transformer that is a low-frequency transformer is an iron core transformer, in this study using a used UPS transformer. In this study, the inverter using an input voltage of 12V DC produced an inverter power of 140 watts and a frequency of 50 Hz. The results of tests conducted on the ASPER-19 robot obtained a relatively stable output voltage of 221.5 V with a frequency of 50 Hz and a THD value produced below 5%.
