Associate Professor Dr. Mohd Mawardi develops wireless LEDs as a source of white light (photon) for photocatalytic reactor applications
Researchers from the Faculty of Electrical and Electronics Engineering Technology (FTKEE), Universiti Malaysia Pahang Al-Sultan Abdullah (UMPSA), Associate Professor Dr. Mohd Mawardi Saari, 37, have developed a photocatalytic reactor using LEDs as a white light (photon) source. A wireless power transfer system powers these LEDs and moves freely within the reactor to activate the photoreforming process by the photocatalyst.
“In my research titled ‘Fluidized Wireless LED Reactor (Wastewater Treatment and Hydrogen Production), this product works by converting DC electrical energy to AC at high frequency using an inverter specifically developed for this project.
“This AC electrical energy is then transmitted to the transmitter coil outside the reactor to uniformly convert the electrical energy into magnetic energy within the reactor.
“Then, through the induction concept, this magnetic energy is received by the receiver coil and converted back to electrical energy to power the LED,” said Dr. Mawardi, who holds a Doctorate (Engineering) from Okayama University, Japan.
Associate Professor Dr. Mohd Mawardi stated that the LED will then convert electrical energy into light (photon) to activate the photocatalyst for the photoreforming process.
