Abstract:
1. A driving device to drive a first load and a second load, the driving device comprising: a power source that converts input power to output power, an output of the power source being connected to the first load and the second load; a first capacitor connected to the output of the power source; a second capacitor connected to the output of the power source; a load selector that opens and closes a circuit of the first load and a circuit of the second load so as to alternately close the circuit of the first load and the circuit of the second load such that the load selector closes the circuit of the second load after the opening of the circuit of the first load; and a capacitor selector that opens and closes a circuit of the first capacitor and a circuit of the second capacitor so as to alternately close the circuit of the first capacitor and the circuit of the second capacitor such that the capacitor selector closes the circuit of the first capacitor in synchronization with the closing of the circuit of the first load by the load selector, and such that the capacitor selector closes the circuit of the second capacitor in synchronization with the closing of the circuit of the second load by the load selector, wherein the capacitor selector opens the circuit of the first capacitor after the opening of the circuit of the first load by the load selector and before a next closing of the circuit of the first load by the load selector.
