摘要： A controller for dimming control of a switching power supply includes a phase angle measurement block and a drive logic block. The phase angle measurement block is to be coupled to receive an input sense signal. The phase angle measurement block generates a phase angle signal representative of a phase angle of an input voltage of the power supply in response to the input sense signal. The drive logic block is to be coupled to control switching of a switch included in the power supply. The drive logic block controls the switch in a closed loop dimming control when the phase angle is less than or equal to a phase threshold and in a open loop dimming control when the phase angle is greater than the phase threshold.

摘要： A phase switched power controller connects a load to a alternating current source for a proportion of each half cycle selected by the user. A first full wave rectifier is connected to the voltage source and produces an unfiltered full wave rectified output signal varying between zero and a predetermined peak. A low pass filtered full wave rectified signal is preferably obtained from a second full wave rectifier, the filtered voltage and unfiltered voltage being applied as inputs to a voltage comparator, the output of which triggers a timer. The timer determines the phase delay until a further pulse is triggered for activating a triac, applying power to the load during the remainder of each half cycle.

摘要： A switching arrangement for full-wave power control comprising a triac (2), the control electrode of which is preceded by a trigger diode, the control voltage being taken from an RC section having at least one potentiometer (9), which effects a phase shift in the firing time as a function of the position of the potentiometer (9), is improved by the RC section (9, 10) being connected to a constant voltage source. This consists of two Z diodes (6) which are connectd in opposition and which are advantageously bridged by means of an adjustable voltage divider (7, 8), in such a manner that the RC section (9, 10) is connected to an adjustable part voltage. Instead of bridging the triac (2) for full drive, as usual, the trigger diode (11) is connected to a special bias resistor by means of a switch (13). According to a preferred embodiment, the resistors of the switching arrangement consists of a low-temperature thick-film paste printed on a hard paper board (see drawing relating to this).

摘要： A switching regulator and method of regulating an ac input signal to provide an ac output signal, receiving the ac input signal, generating a reference signal, detecting the points when the ac input signal is zero and synchronising the reference signal to these points, performing a subtraction between the reference and ac input signals to obtain an error signal, dividing the error signal by the reference signal to obtain a fractional error, and producing a regulated ac output signal by modulating the ac input signal to correct for the fractional error. The switching regulator uses a modulating transistor and clamping diode for each half-cycle of the input signal.

摘要： An appliance is provided with an improved power management system for controlling the total amount of current provided to at least a first load device of the appliance. The power management system is comprised of a microprocessor, an alternating current voltage source, a voltage regulating circuit, a clamping circuit, at least one load device, and a MOC and a triac for each of the at least two load devices. The clamping circuit outputs a fixed voltage of 5.7 volts during the positive portion of the ac cycle and a fixed voltage of −0.7 volts during the negative portion of the ac cycle. The fixed voltages are input to a microprocessor which utilizes these inputs to control the average voltage and the amount of time the current is turned on to each of the at least first and second load devices. A current sensing circuit is used to monitor the current to one of the at least two load devices to provide feedback to the microprocessor so that the microprocessor can adjust the average voltage and current to the at least two load devices so that the total current consumed does not exceed a pre-determined level.
