This paper presents the simulation and experimental of class-E power amplifier. It’s is often used in designing a high frequency ac power source because its ability to perform the conversion efficiently even when working at high frequencies with significant reduction in switching losses. Class-E power amplifier is connected with both air core transformer and iron core transformer. This paper aims to compare the transmission performance of electrical power between the air core transformer and iron core transformer which input voltage equal 50 VAC. Both transformers are designed to step voltage up (step up transformer) ratio of 1:3.29. The microcontroller arduino is used to generate a pulse width modulation (PWM) with operating frequency of 3.9 KHz. And IC gate drive TC4422 is used to drive the IRF510 MOSFET. From the simulation and experimental results, power loss in air transformer about 75 percent while power loss in iron core transformer about 0.2 percent. And the maximum distance that can transmit electric power of air core transformer is 9.3 centimeters.
