The invention relates to an electric circuit (10), in particular for a medium voltage power converter. The circuit (10) has at least four semiconductor switches (15, 16, 17, 18) which form a series connection and which are connected to poles of a direct current voltage (Ud). A diode ...
aAn eletric circuit often consists of four parts:a source or power supply such as a battery,the conductors or wires,the control device such as a switch,and the load.the load is a device or a machine.Within the lode the actual energy conversion takes place.The lamp,the resistor and motor...
(usually very small and can be neglected) Control circuit Detection (measurement) circuit drive circuit Power circuit (power stage, main circuit) Control circuit (in a broad sense) Power electronic system: Electric isolation: optical or magnetic Protection circuit is also very often used in power ...

The LC circuit’s resonance h attains the electromagnetic frequency useful in several applications, including the telecommunication technology. The tank can possibly be charged to a certain resonant frequency through the adjustment of reactive element data. In addition, the essential phase of the ...
At least one of the MOSFETs in each of three sets of the six sets has a separately metallized current-sensing pad. The output from this pad represents the phase current. When phase current reaches a maximum permissible level, this signal controls the MOSFET gates to limit current.ハリミ エ...
Furthermore, the importance of transients in power systems is receiving more and more attention in recent years as a result of various blackouts, brownouts, and recent collapses of some large power systems in the United States, and other parts of the world. As electric power consumption grows ...
