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 star-connected secondary. Neutral point N…
Voltage Multipliers - Voltage Doublers, Triplers and Quadruplers Voltage multipliers is a modified capacitor filter circuit that delivers a dc voltage twice or more times of the peak value (amplitude) of the input ac voltage.…
What is Bleeder Resistor? - Working and Its Functions The operation of an inductor filter is based on the fact that a minimum current flows through it at all times. To provide flow of this…
What is Surge Current? - Definition and Workings Before switching on of power supply, the filter capacitor is uncharged [Fig. 9.23]. At the instant the power supply is switched on, the uncharged capacitor behaves like…
