N2 - This paper proposes a three-phase electronic ballast with current-equalization function. By properly designing the resonant tank and the values of the resonant inductance and resonant capacitance, the current difference between lamps can be significantly reduced. Hence, current-equalization can be achieved by means of impedance-matching. Without an additional current-equalization circuit, the cost of the proposed circuit is reduced due to fewer components. The analysis and design of the proposed circuit will be presented in this paper. Finally, the proposed three-phase electronic ballast with current-equalization function will be implemented to validate and demonstrate the performance and feasibility of the proposed circuit.
