摘要
An automatic furnace comprises an actuator for an electric igniter. The electric igniter has a distinctly lower standard voltage, e. g., 120 V, than the network voltage, e.g., 230 V and is operated by the network voltage. The network voltage is fed into the power regulator before the igniter. The power regulator clocks the network voltage with an adjustable keying ratio, so that only part of the full wave trains of the network voltage becomes active at the electric igniter. In an advantageous embodiment, the keying ratio is variegated by the actual level of the network voltage.
