Rectifiers Seller in Bangladesh

Rectifiers are essential components that convert alternating current (AC) into direct current (DC). They find applications in power supplies, battery charging, welding machines, and many other systems that require stable DC voltage. There are two main types of rectifiers: half-wave rectifiers and full-wave rectifiers.

  • Half-Wave Rectifiers: These rectifiers allow only one half of the input AC waveform to pass through, resulting in pulsating DC output. They are simple and cost-effective but have lower efficiency due to the wastage of half of the input power.
  • Full-Wave Rectifiers: Full-wave rectifiers, on the other hand, utilize both halves of the input AC waveform, resulting in smoother DC output. They can be further classified into two types: center-tapped and bridge rectifiers. Bridge rectifiers, which consist of four diodes in a bridge configuration, are more commonly used due to their higher efficiency.

Diodes Seller in Bangladesh

Diodes are fundamental semiconductor devices that allow current to flow in one direction only. They play a crucial role in power electronics by rectifying AC signals, protecting circuits from reverse voltage, and regulating voltage levels. One of the most common types of diodes is the P-N junction diode, which has two layers: P-type (positive) and N-type (negative).


When a voltage is applied across the diode in the forward direction (anode to cathode for P-N diodes), it allows current to flow easily. In the reverse direction, the diode blocks current flow, thus protecting the circuit from potential damage. Best Price IGBT Rectifier SCR Diode Seller in Bangladesh in who is?
