RANCANG BANGUN RANGKAIAN FULL BRIDGE CONVERTER DAN THREE PHASE INVERTER SEBAGAI PENGGERAK MOBIL LISTRIK BERBASIS MIKROKONTROLLER (FULL BRIDGE CONVERTER)

摘要

Using induction motor as the propulsion of electric car needs some converter and inverter as speed controller. To fulfill 3 phase induction motor supply voltage we need 3 phase inverter as speed controller and also power converter as 3 phase inverter constant supply voltage 220 Volt dc Topology of power converter that suitable in electric car application is Full Bridge Converter because it is able to produce high power about 5 kW and supporting by high frequency so the motor will supplied fast. This Full bridge converter used to increase voltages and supplied constantly. This converter was designed with 70 volt input voltage from 6 units of accumulator with each specification is 12V/36 Ah and will be supplied the induction motor 220V that pass the inverter before as speed controller with adjusting the frequency. From the converter�s experiment result that is triggered by PWM(Pulse Width Modulation) generator with frequency 40kHz and duty cycle 50% with three phase induction motor 1 Hp as load we got output voltage equal with 183 Volt dc and output current equal with 0,1 A .
