aThe first method used to increase the efficiency was to eliminate the galvanic isolation typically provided by high-frequency transformers in the DC–DC boost converter or by a low-frequency transformer on the output. Thus a typical efficiency increase of 1–2 % can be obtained. 第一个方法在...
aZ-source inverter can boost dc input voltage with no requirement of dc-dc boost converter or step up transformer,hence overcoming output voltage limitation of traditional voltage source inverter as well as lower its cost. A comparison among conventional PWM inverter, dc-dc boosted PWM inverter,...

supply. The primary and or secondary of the transformer is switched or shorted for the lower speeds. The system uses the full capacity of the rectifiers even at low motor speeds so that cable runs can be kept to an optimum thickness and an efficient performance assured. The transformer ...
In this article, we’ll take a look at circuit design from the transceiver to the can-bus connector. It’s time to get our hands dirty and design our CAN-bus circuitry! Step One - Choose the Right IC All CAN-bus transceivers operate similarly, as they sit between the microcontroller (...
