Latest Patents

Nils Bäckman holds a patent for a zero-voltage-switching (ZVS) snubber circuit. This circuit is specifically designed for high power boost converters that are utilized as power factor correction circuits in AC-to-DC modules. The ZVS circuit features a main switch, an auxiliary switch, a load circuit, a reset circuit, a first diode, a blocking diode, and a first capacitor. The configuration allows the switches and the capacitor to be connected in parallel. Notably, the circuit includes a blocking diode that connects to the auxiliary switch, ensuring that at turn-off, the current tail of the main switch is managed by the auxiliary switch. This design minimizes the turn-off loss by keeping the collector-emitter voltage of the main switch nearly zero.
