回路（２）の負側でなく正側に接続しても同様の動作と
なることは当然である。For this reason, 1. For example, when a discharge lamp is lit, it is possible to reduce the relatively low and flat DC voltage period, such as the supply period from the auxiliary DC power supply in the conventional device (see Figure 4). It is expected that the luminous efficiency of the discharge lamp will be higher than that of conventional devices. Naturally, the same operation will occur even if one end of the capacitor is connected to the positive side of the full-wave rectifier circuit (2) instead of the negative side.

半サイクル毎の非対称さが大きくなり不適当である。In the device of the present invention, if the charging voltage for the capacitor (2N) is not set to approximately 1/2 of the voltage of the AC power supply (1), there will be a lot of ripple as shown in Figure 6), and the voltage will be half the voltage of the AC power supply (1). The asymmetry between cycles becomes large, which is inappropriate.

てしまうなど本発明の目的とするところではない。A small capacitor may be connected in parallel to the inverter (3), that is, between the output terminals of the full-wave rectifier circuit (2) for the purpose of lowering the high-frequency impedance, but the capacitance is twice that of the AC power supply (1). Connecting a large-capacity capacitor that smoothes the frequency component of is not the purpose of the present invention, as it would result in a significant drop in the power factor.
