This paper proposes a method to reduce the dc link capacitor of the ISG(Integrated Starter Generator) inverter for the micro-hybrid system of which ESS(Energy Storage System) is composed of a 12V battery, a 60V supercapacitor and a bidirectional DC-DC converter. Firstly, analysis is performed to calculate the required dc link capacitance according to the allowable voltage ripples and some inverter switching frequencies. And then, a method is presented in which is increased the switching frequency, namely decreasing the switching period smaller than the current control period, to reduce the voltage ripple. Thirdly, another method is presented to compensate the ripple voltage with a bidirectional dc-dc converter which is controlled in the analog manner. Finally, several simulations are done to verify the effectiveness of the proposed method. Using the proposed method, the required capacitance can be reduced to a half of that of the initial design in the worst case.
