(57) Abstract Topic Method and the device which decrease the electrical loss which originates in the switching of the switch mode electrical converter are offered. Solutions The electrical converter of this invention, each through the inductor (20, 26, 220 and 226) to the common node (30), the plural switch aggregates (14, 16, 214 and 216) which are connected, the diode (22, 28, 222 and 228) which is connected to the 2nd common output node (34), has the switch & the controller (12, 212, 412, 612 and 812) in order it activates and to inactivate the plural switch aggregates and between the switching cycle which is continued. The controller, between each switching cycle 1 times, activates and inactivates each switching aggregate and activates one small group of the switch aggregate before the activating the remaining switch aggregate. The switch & the controller the switch aggregate in the plural switch aggregates which the remaining switch aggregate compared to are activated before give the possible conversion signal in order to alternate. The switch & the controller have one which gives the signal which is delayed timewise vis-a-vis the modulator and the modulating signal which modulate the required signal and the clock pulse delay circuit at least.
