Abstract:A new analytic method for calculating inverter bus capacitor and DC Reactor parameters was proposed in this paper. In the realization process, ripple current, life of DC bus capacitor, interaction between DC bus capacitor and DC Reactor were considered comprehensively. The design scheme of DC bus capacitor and DC Reactor, specific parameters such as capacitance, loss, ripple current, central average temperature, life, connection mode of the capacitor and inductance, ripple current, loss, size, the reactor were given. On this basis, a variable frequency speed control system was designed, the calculated value, empirical value and experiment value were compared, and calculated value was to make volume of the inverter smaller on the premise of ensuring output. It had affirmed precision of the analytical method and verified correctness and feasibility of this method.
