Abstract
A method of controlling several clocked loads controllable individually and independently of each other, more particularly heating loads of an electric oven, for minimizing the demand on an alternating current mains due to switching transients. More particularly, the loads are energized in sequence to prevent flickering when the loads are coupled to a common phase of the alternating current mains are switched on each time at the beginning of their clock period. The clock periods of the various loads are of equal length. All loads neither switched off nor switched to full power in a switching cycle are connected to the mains so as to be interlinked in time in a manner such that, when the preceding load is switched off, the next load is switched on. Such a switching cycle is started again each time at the beginning of a common clock period independently of the length of the switching cycle.
