Abstract
A power converter circuit (1) and an associated method of converting an AC power supply. The power converter circuit (1) comprises: a supply rectifier circuit (2) for rectifying an AC supply power to generate a rectified supply power; an inverter circuit (3) for receiving the rectified supply power to generate an inverted supply power; a load rectifier circuit (4) for rectifying the inverted supply power to generate a rectified load power for supplying a load current to a load (5); and a charge pump circuit (6) driven by the load current to pump additional charge to the rectified supply power.
Claims24
A power converter circuit comprising:
- a supply rectifier circuit for rectifying an AC supply power to generate a rectified supply power;
- an inverter circuit for receiving the rectified supply power to generate an inverted supply power;
- a load rectifier circuit for rectifying the inverted supply power to generate a rectified load power for supplying a load current to a load;
- and
- a charge pump circuit driven by the load current to pump additional charge to the rectified supply power, the charge pump circuit comprising a first capacitor connected between the supply rectifier circuit and either the load rectifier circuit or an output of the inverter circuit.
A method of converting an AC supply power, the method comprising:
- rectifying the AC supply power to generate a rectified supply power;
- inverting the rectified supply power to generate an inverted supply power;
- rectifying the inverted supply power to generate a rectified load power for supplying a load current to a load;
- and
- using the load current to pump additional charge to the rectified supply power by connecting a first capacitor between the AC supply power and either the inverted supply power or the rectified load power.
