Three Phase Rectifiers

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 of the secondary forms the negative terminal for the load and is earthed, as illustrated in Fig. 9.11. Input and […]

Voltage Multipliers – Voltage Doublers, Triplers and Quadruplers

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. Such power supplies are used for high-voltage and low-current devices such as cathode-ray tubes (the picture tubes in TV receivers,
