The operation of the present invention will be explained below with reference to FIGS. 1 and 2. In Figure 1, when switches SWI and SW2 are closed from the open state, auxiliary relay X and diode D
The Dl side of the capacitor C, which had been charged to the E, (V) side (point A in Figure 2) through 1, instantaneously changes to Ov (point B in Figure 2). At this time, the diode D2 side terminal of the capacitor C connects the cathode of the diode D2 to Ov, so the discharge current does not flow from Ov, and if we ignore the forward voltage of the diode D1, we can calculate -E, (V) from Ov. (point C in Figure 2), and since SW2 also closes at the same time as SWI, auxiliary relay
A voltage 2E, (V) twice that of (V) is applied momentarily (
(Figure 2 from point F to point G). At this time, auxiliary relay
A discharge current ICX determined by the coil resistance RX of the auxiliary relay, the capacitance of the capacitor C, and the control power supply voltage E, (V) flows so that the capacitor charging voltage -E o (v) becomes 0 (V), and this current ICX has a charging voltage of -E, (V
) until it reaches O(V) (from the second plot point to the E point). After that, the control power supply voltage E a is applied to the auxiliary relay
(V) and the current I determined by the coil resistance RX of the auxiliary relay
X flows. In other words, the voltage applied to the auxiliary relay X changes from 2E, (V), E, (V) while the discharge current XCX is present (from point G to point H in Figure 4), and after the discharge ends, the control in the conventional technology It becomes the same as the power supply voltage E O (V) (4th
Since the voltage applied to the auxiliary relay X increases due to the discharge of the capacitor C, as shown in point H in the figure, the operation time is α time earlier than the operation time T1 in the prior art.

Also, the voltage applied to the auxiliary relay X is 2E, (V) at maximum, but after the auxiliary relay Fever is suppressed.

As explained above, it is possible to increase the speed of the auxiliary relay without increasing the control power supply voltage.
