Single Stage Amplifier Frequency Response and Phase Response Curves: The voltage gain of a single-stage transistor amplifier commences to fall off at some high frequency. This fall-off may be due…
Three Phase Cycloconverter - Types, Working and Applications: A cycloconverter converts ac at one frequency to an ac of another frequency. Cycloconverters can be classified as single-phase to single-phase, three-phase…
Three Phase Converter Circuit: For large sized (rating exceeding 15 kW) motors 3-phase drive is employed. The output voltage of a 3-phase converter has less ripple contents than that of…
Phase Splitter Circuit for Push Pull Power Amplifiers (or Phase Inverter): In a push-pull amplifier circuit an input transformer is used to provide the polarity inversion between the two input…
Phase Reversal in Single Stage Transistor Amplifier: In a common emitter configuration, the output voltage increases in the negative direction when the input signal increases in the positive direction and…
Three Phase Rectifiers: Three-Phase Half-Wave Rectifier : Figure 9.11 illustrates a circuit for a 3-phase half-wave rectifier. The three diodes are connected to the three phases of a 3-phase transformer…
Three Wattmeter and Two Wattmeter Method: In this method, the three wattmeter are connected in the three lines as shown in Fig. 9.45, i.e. the current coils of the three…
Unbalanced Three Phase Circuit Analysis: Types of Unbalanced Loads - An unbalance exists in a circuit when the impedances in one or more phases differ from the impedances of the…
