A system and method are provided for using dynamic random access memory and flash memory. The titanium oxide exhibits a high photocatalytic activity by visible light radiation. The modifier is capable of producing free radicals when heated to scavenge free radicals generated from thermal cracking or burning of the polymer material to prevent further thermal cracking of the polymer material. The current source is connected to an output of the operational amplifier. The method also includes executing an inverter control algorithm and a DC-to-DC converter control algorithm to generate drive signals for the inverter and DC-to-DC converter, respectively, based on the received commands and feedback signals.
