A diode bridge is a bridge rectifier circuit of four diodes that is used in the process of converting alternating current (AC) from the input terminals to direct current (DC, i.e. fixed polarity) on the output terminals. Its function is to convert the negative voltage portions of the AC waveform to positive voltage, after which a low-pass ...
A voltage doubler is an electronic circuit which charges capacitors from the input voltage and switches these charges in such a way that, in the ideal case, exactly twice the voltage is produced at the output as at its input. The simplest of these circuits is a form of rectifier which take an AC voltage as input and outputs a doubled DC voltage ...
A variant of this is to use two capacitors in series for the output smoothing on a bridge rectifier then place a switch between the midpoint of those capacitors and one of the AC input terminals. With the switch open, this circuit acts like a normal bridge rectifier. With the switch closed, it acts like a voltage doubling rectifier.
The Vienna Rectifier provides the following features: Three-phase three-level three-switch PWM rectifier with controlled output voltage [3] Three-wire input, no connection to neutral. Ohmic mains behaviour [4] Boost system (continuous input current) Unidirectional power flow [5] High power density. Low conducted common-mode electro-magnetic ...
For 240 V operation, the switch configures the system as a full-wave bridge, re-connecting the capacitor center-tap wire to the open AC terminal of a bridge rectifier system. This allows 120 or 240 V operation with the addition of a simple SPDT switch. A voltage tripler is a three-stage voltage multiplier.
A: Bridge rectifier; B: input filter capacitors; Between B and C: heat sink for switching active components of primary voltage; C: transformer: Between C and D: heat sink for switching active components of at least five secondary voltages, per the ATX specification; D: output filter coil for the secondary with the largest power rating.
Ripple (specifically ripple voltage) in electronics is the residual periodic variation of the DC voltage within a power supply which has been derived from an alternating current (AC) source. This ripple is due to incomplete suppression of the alternating waveform after rectification. Ripple voltage originates as the output of a rectifier or ...
In power supply design, a bridge circuit or bridge rectifier is an arrangement of diodes or similar devices used to rectify an electric current, i.e. to convert it from an unknown or alternating polarity to a direct current of known polarity. In some motor controllers, an H-bridge is used to control the direction the motor turns.
