D1: Rectifier diode
Use a rectifying diode with a peak reverse voltage of 800V or higher,
an average rectification current of 1A or larger and a peak surge
current of 20A or larger. When using a large capacitance input capacitor,
select a component that is strong against inrush current during power up.
Full-wave rectification can be used.
10 to 22Ω 1/4W
R1: Noise reduction resistor
ZNR: Varistor
Determine the ideal value through actual testing.
A varistor is required to protect against lightning surges and static
electricity.
