![]() ![]() ![]() The PWM rectifier is controlled in a way that a sinusoidal AC line current is drawn, which is in phase or anti-phase (for energy feedback) with the corresponding AC line phase voltage.ĭue to the DC-link storage element, there is the advantage that both converter stages are to a large extent decoupled for control purposes. The DC-link quantity is then impressed by an energy storage element that is common to both stages, which is a capacitor C for the voltage DC-link or an inductor L for the current DC-link. Such phase-controlled thyristor-based rectifiers however have higher AC line distortion and lower power factor at low load than diode-based rectifiers.Īn AC-AC converter with approximately sinusoidal input currents and bidirectional power flow can be realized by coupling a pulse-width modulation (PWM) rectifier and a PWM inverter to the DC-link. Alternatively, an anti-parallel thyristor bridge must be provided in the rectifier section to feed energy back into the AC line. 3): In CSI converters, the rectifier consists of a phase-controlled switching device bridge and the DC link consists of 1 or 2 series inductors between one or both legs of the connection between rectifier and inverter.Īny dynamic braking operation required for the motor can be realized by means of braking DC chopper and resistor shunt connected across the rectifier. Current-source inverter (CSI) converters (Fig.2): In VSI converters, the rectifier consists of a diode-bridge and the DC link consists of a shunt capacitor. Voltage-source inverter (VSI) converters (Fig.There are two types of converters with DC link: Appointments are available seven days a week.Fig 3: Topology of current-source inverter AC/DC-AC converter Jackie is based in Kent, home visits are available across Kent, South-East London, Essex, Sussex, Surrey and the surrounding areas. To get your personal life skills dog training journey started book today and remember, sessions can be held at your home, surrounding environment or at our secure, gated outside training centre here in Kent so please let Jackie know your preference upon booking. Examples of commonly occurred problems and where Jackie can help you include: pulling on the lead, housetraining, new dog ownership, not returning when called, basic manners and obedience, chewing, jumping up at guests in the house, aggressive behaviour, child and dog relationships, new baby or pet introductions, excessive barking, mouthing and nipping, advanced manners and obedience, pulling towards other people and more!Įveryone, owners and dogs, no matter the age, breed or size, are welcome to sign up to this course as this dog training package will set you on the right path, with your own dog training expert to help you with your training, a tailored dog training programme to help you achieve your end results and goals with support in between sessions. Helping several owners with their dog training needs, Jackie will develop a dog training programme and plan to help you conquer the problems and achieve your end results. All training will involve Jackie teaching you how to best communicate with your dog, without using fear, submission and intimidation but using reward-based techniques.ĭevelop expertise and confidence by immersing yourself in this one-to-one dog training course and techniques to master the skill of overcoming your problem areas. ![]() Jackie will devised a personal dog training package for you and your dog, a package that is tailored and customised to your exact needs and consists of three lessons spread over a 5-6-week period, known as life skills training, setting you and your dog up with essential skills, knowledge, commands and techniques to last a lifetime. One to one dog training is also an ideal solution for certain dog training needs as they are more effectively and appropriately addressed in private lessons, rather than in a group dog training class. Our one-to-one dog training course is perfect for owners who love the convenience of lessons in their own home and for dogs who don’t learn well in a class environment. One to one Dog training in and around Kent with an expert educate your dog and learn essential skills from Jackie Murphy with her private one-on-one dog training package, available across Kent, South-East London, Essex, Sussex and Surrey. ![]()
