Abstract

Inverter is an electronic circuit that convert electric voltage with direct current (DC) to alternating current (AC). One of the commonly used inverter configuration is H-Bridge circuit. Inverter with H-Bridge circuit does not need voltage-balanced diode or capacitor to operate and can be cascaded to obtain multilevel output voltage. H-Bridge circuit works by adjusting the combination of switches that were enabled. One of the commonly used switches is Metal Oxide Semiconductor Field Effect Transistor (MOSFET). The advantages of MOSFET as switching components are its fast switching speed and it did not cause current tail. Therefore, the writing of this paper aims to design a 12V DC to 220V AC 50Hz single-phase inverter with H-Bridge MOSFET circuit. The design stage begins with determining the specifications of the inverter, creating a block diagram of the inverter, determining the required components, and calculating the required parameters of the inverter. The designed inverter is simulated using Proteus 8.4 software. Simulation results are in accordance with the desired specification.

Abstract

Based on Law Number 1 of 1970 concerning Occupational Safety is not only applied in industry, but in all workplaces, it is mandatory to apply Safety and Security (K3), one of which is in education both at school and college levels which have a high risk of danger. The cause of work accidents occurs due to Unsafe Action factors reaching 88% and 10% Unsafe Conditions. Health and Safety Executive data states that 90% of accidents are caused by human error. The purpose of the research is to design AC and DC electrical safety training modules that can be used as practicum media for students in understanding the basic principles of electrical risk control and prevention of explosion hazards due to errors in electrical systems. The engineering and development method is the design and fabrication of training modules, which consist of AC and DC electrical devices, equipped with risk control systems such as automatic circuit breakers, grounding systems, and short circuit protection. The results show that the circuit design consists of 2 circuits, namely AC and DC circuits. The circuits can be separated and can be combined by considering making it easier to carry out practicum and maintenance processes to prevent failures in the system that can cause accidents.
