摘要： Apparatus for regulating a d.c. voltage appearing across a load. The emitter-collector junction of a transistor is connected in series with a retardation coil and with the load impedance to a d.c. voltage source. The voltage applied to the load impedance is compared with a reference voltage in a regulating circuit. The latter circuit provides an output signal of a value which is a function of the d.c. voltage appearing across the load impedance. The conductivity of the emitter-collector path of the aforementioned transistor is controlled by the latter output signal. An adjustable impedance is connected in series with the primary winding of a transformer and to the voltage source. The secondary winding of the transformer is connected across the base-emitter junction of the aforementioned transistor, and the signal appearing across this winding controls the operation of the transistor. A frequency generator produces a timing signal, which through the regulating circuit, produces an edge of the output signal. The other edge of the output signal is a function of the d.c. voltage appearing across the load impedance.
