Abstract

An electrical power controller includes a boost converter, an invertor and an output section. The boost converter includes a control circuit which charges a capacitance from an inductance in accordance with a stream of pulses having a variable duty cycle. A feedback circuit responsive to the power consumed by a load provides an error signal for varying the duty cycle of the pulses. In the invertor, a pair of switches sample the charge on the capacitor to create an AC signal which is introduced to the output section. The sampling frequency in the boost converter is related to the sampling frequency in the invertor by an integer.
