Abstract: PROBLEM TO BE SOLVED: To provide a loop-type voltage regulating device for regulating the voltage, especially of an automatic electrical system. SOLUTION: This device is of such a type, that it includes at least one heat engine (15), a voltage regulator (13), and a synchronous generator (11) capable of operating to provide the regulated voltage signal (A+) of the system and to receive a regulation signal (DF) from the voltage regulator (13), for a loop- type voltage regulating device for regulation of the voltage, especially of an automatic electrical system. This voltage regulating device advantageously includes further a control unit (14) within a regulation loop, and the unit is connected between the heat engine (15) and the voltage regulator (13), and also it is applied to supply the latter (the voltage regulator) with a signal related to engine operation.

Abstract: PURPOSE: To detect a malfunction of a drive circuit without impeding a normal operation of the drive circuit by directly connecting a malfunction detector with an output terminal of the drive circuit. CONSTITUTION: A malfunction detecting circuit 10 comprises an input terminal 3 connected with an output terminal 4 of a drive circuit 1, an output terminal 20 for feeding a digital signal which indicates a connecting condition between the drive circuit 1 and a load 5, and a detector for detecting when a malfunction occurs between the drive circuit 1 and the load 5. When a control signal IN is switched to an L level, a delay circuit 24 generates an output pulse which operates a transistor 23. In this manner, irrespective of the value of a voltage V1 , the output terminal 20 is grounded so that an output of the AND circuit becomes the L level. When the pulse generated by the delay circuit 24 is terminated, the transistor 23 is turned off. Since an output terminal of a comparator 15 can be switched to a logic condition which corresponds to a level of a voltage V1 , an output terminal of a circuit 25 generates an H signal at the time of occurrence of the malfunction and generates an L signal when the load 5 is connected. The type of malfunction can be identified by a malfunction identifying circuit 12.

Abstract: A double half-wave rectifier circuit with earth shift using an input differential amplifier (A1) and two current mirrors (CM1, CM2) in cascode configuration in such a way that the input current (I) is transferred to the output via one or the other of the current mirrors (CM1, CM2) depending on whether the input signal voltage (Vin) is greater than or less than an input reference voltage (Vrefin) and therefore the current (I) is positive or negative.
