PHASED POWER CONTROLLER Russian patent published in 2007 - IPC G05F1/66 H02M5/257 

FIELD: electric engineering, possible use, for example, for smooth launch of electric motor with limited launch current and possible control over rotation frequency, for control and stabilization of incandescent lamps or room brightness, for stabilization of given temperature in electric furnaces, water heating or heating systems, or with stabilization of temperature of heated premises, for controlling and stabilizing electric average power, current or voltage of consumption of active or inductive load, of practically any power, meant to be connected to one or several phases of network power.

SUBSTANCE: phase power controller contains load, controlling key element - symistor, network power source, impulse generator with phase-shifting circuit, control block with time-setting circuit in output cascade, thermo-controller. Introduced to device are alternating resistor being the power controller, power block, impulse generator additionally contains discharge cascade of phase-shifting circuit generator, control block is complemented with resistor, two cascades for controlling discharge of time-setting circuit capacitor, while time-setting circuit is complemented with two resistors of time-setting circuit. Connection of introduced elements is performed in accordance to formula of invention.

EFFECT: possible connection of additional blocks, controllers and elements to device to connect load to several network power phases, expanded functional capabilities of suggested phased power controller with following additional functions: electronic disabling of load with possible preliminary smooth (time-wise, up to several seconds) decrease of electric power, stabilization of average current or voltage in load or limiting of aforementioned parameters while preserving manual control output power; stabilization of given brightness of room or heating temperature, when incandescence lamp or heating element represent the load.
