Definitions

  • This invention relates to power supplies where power can be drawn from a battery or a mains input such as occurs in caravans or boats for example.
  • the invention consists in a power supply including a battery input, a mains input, a boost regulator connected to the battery input and the mains input and having an output for providing a DC signal, a DC/AC driver responsive to the DC signal for providing an AC output signal characterised in that the supply further includes a controller for monitoring the battery input level and the mains input level and adjusting the boost regulator output in accordance with the respective detected input levels.
  • the controller may be arranged for monitoring the rate of charge of the battery. It may for example be arranged for causing the boost regulator to maintain at least a level of supply on its output, if the battery is still charging. Conversely the controller may additionally or alternatively be arranged to boost the output of the boost regulator, if the available inputs exceed a predetermined level.
  • the invention also includes a method of operating a power supply as set out above wherein the controller varies the boost regulator output within a range in accordance with the level of supply at the inputs. This may be between 50% - 150% of the normal operational output.
  • the controller may additionally or alternatively switch off the boost regulator when the supply on the inputs falls below a predetermined level.
  • the Applicants have realised that by suitably selecting the operating range of the boost regulator, they are able to maintain vibration over longer periods and are able to boost the amplitude of this vibration when it is convenient and necessary.
  • the need for such an approach may be in part determined by a monitoring system such as described in our co-pending application GB1 1 19330.7 filed 9 November 201 1 and entitled Anti-Fouling System, the contents of which are incorporated by reference.
  • a power supply generally indicated at 10 is illustrated.
  • This power supply is labelled in terms of it being for a boat and having transducers which are driven. This is a particularly effective environment for the power supply described but as indicated previously, the power supply may be efficacious in other environments and for other purposes.
  • the power supply 10 has a DC input 1 1 and a mains input 18. These each feed into a boost regulator 19 that in turn feeds a DC to AC transducer drive 20.
  • the DC to AC transducer drive receives a oscillating signal from a microprocessor 21 and the frequency may be varied for reasons given in the above mentioned co-pending application.
  • Each input 1 1 , 18 has a respective associated A/D converter 22, 23 that feed a respective signal to the microprocessor 21 indicating the status of their respective supply.
  • the microprocessor or controller 21 generates a control signal on line 24 that is fed to the boost regulator 19. From the inputs fed from 22 and 23 the microprocessor can determine if mains power is available; if the DC batteries are being charged by the mains supply, by a charging circuit not shown and what the relative levels of these supplies are.
  • the microprocessor may boost the power supplied to the transducers (or other power consumers) on output 25 particularly if the microprocessor has noted that a previous period of poor supply has preceded the good supply. Equally if battery levels are beginning to drop, but are still at a greater level than is necessary for emergency, then the microprocessor may prolong the period of operation of the transducers by gradually reducing the level of output from the boost regulator 19 or moving it swiftly to near or at 50% of the normal output. If the supply drops below a threshold level, the boost regulator 19 is switched off and an alarm given.

Abstract

L'invention concerne une alimentation électrique (10) comprenant une entrée de batterie (11), une entrée de réseau (18), un régulateur d'amplification (19) connecté à l'entrée de batterie et à l'entrée de réseau, et comportant une sortie pour fournir un signal CC, et un actionneur de transducteur CC/CA (20) réagissant au signal CC afin de fournir un signal de sortie CA. L'alimentation comprend en outre une unité de commande (21) afin de contrôler le niveau d'entrée de la batterie et le niveau d'entrée du réseau, et d'ajuster la sortie du régulateur d'amplification en fonction des niveaux d'entrée détectés respectifs.
