Invertero variable amplitude. Contrary to controlled rectifiers, inverters require switches that can be turned on . at will at any instant. Nowadays, the switches used in inverters are mainly Mosfets (for lower power), IGBTs or IGCTs (for very high power).

Direct Current Commutator Machines) are the inspiration for modern drive control schemes for rotating field machines. Starting from the basic electromagnetic laws, the electromagnetic energy conversion in DC machines is explained. Attention is paid also to commutation and armature reaction. Motoring and generating characteristics are discussed in detail.

One of the last sections is devoted to the operation (mainly as generator) on an infinitely strong grid.

Assessment of mania in bipolar disorder, power (and low output frequencies). In this chapter we review the operating principle, provide some examples of practical three-phase circuits and discuss the main control methods. Important aspects are the output voltage harmonic content and the input current harmonic content and reactive power requirements.
