Definitions
- the invention relates to a series regulator for feeding a DC-powered consumer with means for suppressing the AC component on the supply voltage.
- DE 38 34 880 C2 discloses a control device for suppressing interference signals in the case of a consumer supplied with DC voltage via an actuator. Two control loops are provided there. The total signal consisting of the useful signal and interfering alternating components is compared with a reference signal by means of a first operational amplifier in order to prepare an actuating signal for the actuator. The interference signal is detected by a capacitive sensor and placed in phase opposition at the connection point between the output of the actuator and a resistor leading to the consumer.
- the output voltage is detected via an ohmic voltage divider and fed to an error amplifier, which generates an actuating signal for the actuator from the error deviation.
- the AC component of the output voltage is detected by a capacitor and this is also fed to the error amplifier.
- This series regulator has a separate output smoothing capacitor and is also only suitable for operation with low voltages or potential differences.
- the object of the invention is to provide a series regulator with which high interference suppression is possible. This object is achieved by the measures of claim 1. Claim 9 shows an advantageous application. The further claims relate to advantageous developments of the series regulator.
- the invention only requires a control loop. Instability problems, which occur with several coupled control loops, do not exist in the implementation according to the invention.
- the invention like the arrangement according to DE 38 34 880 C2, permits the regulation of interference signal components which flow past the actuator or the series regulator via parasitic capacitances to ground.
- FIG. 1 shows a series regulator with an actuator in the form of the field effect transistor V1 for supplying a consumer V from a DC voltage supply source Q.
- a separate interference voltage source S is shown for a superimposed Störcicspunng, z. B. the AC ripple US of an upstream switching regulator.
- the connection point of the two voltage sources Q and S is connected to ground via a parasitic capacitance Cp.
- a current feedback resistor R1 is provided in series with the actuator V1, the connection of which faces away from the actuator leads to the grounded output terminal 1.
- the first sensor consists of an ohmic voltage divider with resistors R2, R3.
- An error amplifier N1 is connected with its non-inverting input to the divider tap of the voltage divider R2, R3.
- a reference voltage Uref is applied to the inverting input.
- the actuator V1 works together with the error amplifier N1 and the voltage divider R2, R3 as a conventional series regulator. AC ripples can be suppressed only insufficiently or not at all with this conventional series regulator.
- the second sensor is provided, consisting of the capacitive voltage divider C1, C2 and the capacitor C3, which is connected between the divider tap of the capacitive voltage divider C1, C2 and the non-inverting input of the error amplifier N1.
- the error amplifier N1 is operated with an almost open gain.
- the error amplifier N1 thus only evaluates a small fraction of the output voltage detected by the first sensor.
- the proportion of the second sensor therefore acts by a factor of 100 more on the error amplifier N1 than the proportion of the first sensor.
- the capacitive voltage divider C1, C2 must not deliver a DC component. Only the voltage divider R1, R2 is responsible for the DC component. However, when the high voltage source is switched on, the capacitor C1 is charged. The discharge of the capacitor C1 takes a relatively long time.
- the capacitance of the capacitor C3 is selected to be much smaller than the smallest of the capacitors C1, C2, as a result of which the DC component is quickly masked out. This ensures that the series regulator regulates correctly from the start. In contrast to the implementation according to DE 38 34 880 C2, the small capacitance of the capacitor C3 means that no large capacitive current is necessary.
- the use of the field effect transistor V1 as an actuator in relation to the bipolar transistor according to DE 38 34 880 C2 enables more accurate current detection, since inaccuracies due to flowing base currents are eliminated.
- the capacitance of the capacitor C3 is preferably chosen to be approximately one power of ten smaller than the smallest of the capacitances of the capacitive voltage divider.
