Looking for the bridge rectifier for induction cooker repair? The bridge rectifier is the first power conversion stage in an induction cooktop's power supply — converting incoming AC mains voltage to DC for the IGBT switching circuit. When it fails, the cooktop is completely dead.
What Is a Bridge Rectifier?
A bridge rectifier is a circuit assembly of four diodes arranged in a bridge configuration — converting AC (alternating current) to DC (direct current). In an induction cooktop, the bridge rectifier converts 220–240V AC mains supply to pulsating DC, which is then filtered by large electrolytic capacitors before being used by the IGBT switching circuit.
Bridge Rectifier vs IGBT — Different Failure Points
| Component | Function | Failure Symptom |
|---|---|---|
| Bridge Rectifier | AC → DC conversion | Completely dead, fuse blows, no DC output |
| IGBT | High-frequency switching | Powers on but no heat, fuse blows |
| Resonant Capacitor | LC resonance | No heat, whining noise |
How to Test a Bridge Rectifier
Use a multimeter in diode test mode. Test each of the four diode junctions in both directions — a healthy diode shows forward voltage (0.4–0.7V) in one direction and open circuit in reverse. A shorted diode shows near-zero in both directions.
Key Features

FAQ
Q: How do I know if the bridge rectifier is faulty?
Multimeter diode test — shorted diode (near zero resistance in both directions) confirms rectifier failure. WhatsApp us for step-by-step diagnosis guidance.
Q: Is bridge rectifier replacement DIY?
Requires desoldering the old rectifier and soldering in the new one. Electronics experience and mains voltage safety knowledge required. Recommended for qualified technicians.
