Title:
INDUCTION ELECTRICAL HEATER
Document Type and Number:
WIPO Patent Application WO/1997/001261
Kind Code:
A1
Abstract:
The invention comprises the following elements: a controllable inverter (1) consisting of a controllable master generator (2), a power amplifier (3), a set (4) of current switches and an inductor loop (5); a power supply unit (6); a primary electrical power source (7); a dividing capacitance (8); a first high-voltage divider (9); a unit (10) for monitoring the voltage of the current switch collectors; a generator blocking unit (11); a sensor (12) for detecting the presence of the heated object; a unit (13) for tuning the generator frequency; a power limiting unit (14); a second high-voltage divider (15); a pulsation level determination unit (16); a triggering unit (17); a temperature sensor (18); an audio signalling unit (19); a power control unit (20); and a load temperature sensor (21). The power control unit (20) includes a power regulator (22). The load temperature sensor (21) includes a temperature regulator (23).
