| Summary: | <p align="justify">Wireless charging continues to be developed in an effort to increase the transportation sector .. One method of wireless charging is IPT (inductive power transfer) where the principle is the same as a transformer. In the IPT system itself there are three sub-systems, namely: AC-AC converter, magnetic coupling circuit, and AC-DC converter. The AC-AC converter circuit is connected to the primary part of the clutch circuit while in the secondary part it is connected to the AC-DC converter before it is connected to the battery. This paper focuses on the AC-AC converter component which will convert the source 50 Hz frequency to 50000 Hz on the system. The frequency value is made by adjusting the switching of the MOSFET with the PWM controller. AC-AC converter used in this ciruit is ACAC converter with DC Link which is created and simulated with PSIM software. In addition the AC-AC converter also has a current control circuit that is able to control the input current value of the clutch's primary circuit. Since the circuit will resonate then the load borne by the inverter is just a resistor that causes current and voltage in one phase. In this paper will be made of the design and control current with some cases that used lookup table. In addition, the controls used can also prevent the surge of current values if there is a short circuit in the circuit. This circuit has an average efficiency rating of 85%. <p align="justify"> |
